Refactor database schema: Remove access list and related entities, add editing session and edit operation entities

- Deleted `access_list_entry`, `location`, `proxy_host`, `proxy_host_access_list`, `session`, `stream_service`, `stream_service_access_list` entities and their corresponding migration files.
- Introduced `editing_session` and `edit_operation` entities with appropriate fields and relationships.
- Updated `mod.rs` and `prelude.rs` to reflect the changes in the entity structure.
- Adjusted migration files to remove obsolete migrations and include new migrations for the editing session and edit operation tables.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# Rust API client for agent_client
+
+No description provided (generated by Openapi Generator https://github.com/openapitools/openapi-generator)
+
+
+## Overview
+
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [openapi-spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: 0.1.0
+- Package version: 0.1.0
+- Generator version: 7.18.0
+- Build package: `org.openapitools.codegen.languages.RustClientCodegen`
+
+## Installation
+
+Put the package under your project folder in a directory named `agent_client` and add the following to `Cargo.toml` under `[dependencies]`:
+
+```
+agent_client = { path = "./agent_client" }
+```

+# Migration Tables → nginx mapping
+
+This document explains the purpose of each migration table added under `public/migration/src/migrations` and how the rows map to generated nginx configuration (HTTP `http {}` and `stream {}` contexts).
+
+Summary of tables covered:
+
+- `upstream`
+- `upstream_target`
+- `proxy_host`
+- `location`
+- `stream_service`
+- `access_list`
+- `access_list_entry`
+- `audit_log`
+
+---
+
+## `upstream`
+
+Purpose: A named backend pool of servers. Shared by HTTP and stream services.
+
+Key fields:
+
+- `id`: UUID primary key
+- `name`: identifier used when generating nginx `upstream <name> {}`
+- `protocol`: `http` | `tcp` | `udp` — determines how nginx will use the pool
+- `algorithm`: load balancing strategy (`round_robin`, `least_conn`, `ip_hash`)
+- `sticky_session`: whether to enable sticky behavior when supported
+- `health_check`: optional JSON describing health probes
+
+nginx mapping (HTTP):
+
+```nginx
+upstream <name> {
+    server 10.0.0.5:8080 weight=2;
+    server 10.0.0.6:8080 backup;
+    # optional LB settings generated from `algorithm` and `sticky_session`
+}
+
+server {
+    listen 80;
+    server_name example.com;
+
+    location / {
+        proxy_pass http://<name>;
+    }
+}
+```
+
+nginx mapping (stream):
+
+```nginx
+stream {
+  upstream <name> {
+    server 10.0.0.5:3306;
+    server 10.0.0.6:3306 backup;
+  }
+
+  server {
+    listen 3306;
+    proxy_pass <name>;
+  }
+}
+```
+
+Notes: `upstream.protocol` selects which block and directive forms to generate;
+
+---
+
+## `upstream_target`
+
+Purpose: One row per backend server in an `upstream` pool.
+
+Key fields:
+
+- `upstream_id`: FK to `upstream`
+- `target_host`, `target_port`
+- `weight`, `is_backup`, `enabled`
+
+nginx mapping: each row becomes a `server` line in the generated `upstream` block (weights and backup flags applied). Disabled targets are omitted.
+
+Example generated line:
+
+```nginx
+server 10.0.0.5:8080 weight=3;
+server 10.0.0.6:8080 backup;
+```
+
+---
+
+## `proxy_host`
+
+Purpose: Represents an HTTP(S) host (a top-level `server` block in nginx `http` context).
+
+Key fields:
+
+- `domain`: `server_name` value (may be a wildcard)
+- `listen_port`: port to listen on (80/443)
+- `scheme`: http|https (informs UI; TLS handled elsewhere)
+- `forward_host/forward_port` or `default_upstream_id`: host-level forwarding fallback
+- `preserve_host_header`: whether to forward original `Host` header
+- `enable_websocket`: toggles websocket header handling
+- `meta`: JSON for optional host-level settings (timeouts, client_max_body_size, custom snippets)
+
+nginx mapping (host-level default):
+
+```nginx
+server {
+  listen <listen_port>;
+  server_name <domain>;
+
+  # host-level fallback if no matching location
+  location / {
+    proxy_pass http://<default_upstream_name>;
+  }
+}
+```
+
+If `forward_host`/`forward_port` is set instead of `default_upstream_id`, generate `proxy_pass http://forward_host:forward_port;`.
+
+`meta` entries are injected into the `server` block (careful: snippets can break reloads).
+
+---
+
+## `location`
+
+Purpose: Path-level routing (`location` blocks inside a `server`). More specific than `proxy_host` default.
+
+Key fields:
+
+- `host_id`: FK to `proxy_host`
+- `path`: `location` match (e.g., `/api`, `~^/assets/`)
+- `match_type`: `prefix` | `exact` | `regex`
+- `upstream_id` or `proxy_pass_host`/`proxy_pass_port`
+- `allowed_methods`: optional method whitelist
+- `custom_config`: raw nginx snippet inserted inside the `location`
+
+nginx mapping:
+
+```nginx
+location /api {
+  proxy_pass http://api_upstream;
+  # optional custom_config injected here
+}
+```
+
+Ordering and match type produce correct nginx `location` selection semantics; `order` field can break ties for equal specificity.
+
+---
+
+## `stream_service`
+
+Purpose: A TCP/UDP service in nginx `stream` context — corresponds to a `server` block inside `stream {}`.
+
+Key fields:
+
+- `listen_host`, `listen_port`
+- `protocol`: `tcp` | `udp`
+- `mode`: `direct` | `upstream` (direct forwards to `forward_host:forward_port`, `upstream` uses `upstream_id` pool)
+- `preserved_client_ip`: whether to enable proxy_protocol or other client-ip forwarding
+- `meta`: JSON for advanced stream options (ssl_preread, proxy_timeout, buffer sizes)
+
+nginx mapping (stream):
+
+```nginx
+stream {
+  upstream <name> {
+    server 10.0.0.5:3306;
+  }
+
+  server {
+    listen 3306;
+    proxy_pass <name>; # or proxy_pass 10.0.0.10:3306 for direct
+  }
+}
+```
+
+Notes: Stream services bypass HTTP processing. Use `meta` for `proxy_protocol` and `ssl_preread` toggles.
+
+---
+
+## `access_list` and `access_list_entry`
+
+Purpose: Nameable allow/deny lists for IP/CIDR or other entry types that can be applied to hosts/locations/stream services.
+
+Key fields (access_list): `id`, `name`, `description`.
+Key fields (entry): `access_list_id`, `entry_type` (e.g., `allow`, `deny`, `note`), `value` (IP or CIDR), `comment`.
+
+nginx mapping (HTTP example):
+
+```nginx
+location /admin {
+  allow 10.0.0.0/24;
+  deny all;
+  proxy_pass http://admin_upstream;
+}
+```
+
+nginx mapping (stream example):
+
+```nginx
+server {
+  listen 3306;
+  allow 10.0.0.0/24;
+  deny all;
+  proxy_pass backend_pool;
+}
+```
