## Description
This PR introduces a comprehensive **Connection Reporting System** designed to improve the reliability and monitoring of connections, specifically tailored for environments with restricted internet access (e.g., active censorship, GFW).
### Key Changes
1. **New Reporting API (`/report`)**:
* Added `ReportController` and `ReportService` to handle incoming connection reports.
* Endpoint receives data such as `Latency`, `Success` status, `Protocol`, and Client Interface details.
* Data is persisted to the database via the new `ConnectionReport` model.
2. **Subscription Link Updates**:
* Modified `subService` to append a `reportUrl` parameter to generated subscription links (VLESS, VMess, etc.).
* This allows compatible clients to automatically discover the reporting endpoint and send feedback.
3. **Database Integration**:
* Added `ConnectionReport` schema to `database/model` and registered it in `database/db.go` for auto-migration.
## Why is this helpful for Restricted Internet Locations?
In regions with heavy internet censorship, connection stability is volatile.
* **Dynamic Reporting Endpoint**: The `reportUrl` parameter embedded in the subscription link explicitly tells the client *where* to send connection data.
* **Bypassing Blocking**: By decoupling the reporting URL from the node address, clients can ensure diagnostic data reaches the panel even if specific node IPs are being interfered with (assuming the panel itself is reachable).
* **Real-time Network Intelligence**: This mechanism enables the panel to aggregate "ground truth" data from clients inside the restricted network (e.g., latency, accessibility of specific protocols), allowing admins to react faster to blocking events.
* **Protocol Performance Tracking**: Allows comparison of different protocols (Reality vs. VLESS+TLS vs. Trojan) based on real-world latency and success rates from actual users.
* **Rapid Troubleshooting**: Administrators can see connection quality trends and rotate IPs/domains proactively when success rates drop, minimizing downtime for users.
## Technical Details
* **API Endpoint**: `POST /report`
* **Payload Format**: JSON containing `SystemInfo` (Interface), `ConnectionQuality` (Latency, Success), and `ProtocolInfo`.
* **Security**: Reports are tied to valid client request contexts (implementation detail: ensure endpoint is rate-limited or authenticated if necessary, though currently designed for open reporting from valid sub links).
## How to Test
1. Update the panel.
2. Generate a subscription link.
3. Observe the `reportUrl` parameter in the link.
4. Simulate a client POST to the report URL and verify the entry in the `ConnectionReports` table.
- Add timestamp tracking for each client IP address
- Sort IPs by connection time (newest first) instead of alphabetically
- Automatically disconnect old connections when IP limit exceeded
- Keep only the most recent N IPs based on LimitIP setting
- Force disconnection via Xray API (RemoveUser + AddUser)
- Prevents account sharing while allowing legitimate network switching
- Log format: [LIMIT_IP] Email = user@example.com || Disconnecting OLD IP = 1.2.3.4 || Timestamp = 1738521234
This ensures users can seamlessly switch between networks (mobile/WiFi)
and the system maintains connections from their most recent IPs only.
Fixes account sharing prevention for VPN providers selling per-IP licenses.

When the client has MUX enabled, a TCP or UDP prefix appears before the IP address. We initially weren’t aware of this behavior, but we have now resolved the issue.
* [iplimit] fix access log path in settings service
better to avoid hardcoding the access log path to enhance flexibility. not all users prefer the default './access.log'
* [iplimit] fix iplimit
* [refactor] api controller
* [fix] access log path
better to not hardcode the access log path, maybe some ppl dont want to use the default ./access.log
* [fix] set select options from logs paths in xray settings
* [update] .gitignore
* [lint] all .go files
* [update] use status code for jsonMsg and 401 to unauthorize
* [update] handle response status code via axios
* [fix] set correct value if log paths is set to 'none'
we also use the default value for the paths if its set to none
* [fix] iplimit - only warning access log if f2b is installed
* Reduce outage time on Xray errors
* Improved logs clearing, added previous logs
File name change: 3xipl-access-persistent.log -> 3xipl-ap.log
All previous logs have .prev suffix
* Preparations for tgbot additions
* [tgbot] Improvements, Additions and Fixes
* Changed interaction with Expire Date for Clients
* Added more info and interactions with Online Clients
* Added a way to get Ban Logs (also added them to backup)
* Few fixes and optimizations in code
* Fixed RU translation
* [tgbot] More updates and fixes
* [tgbot] Quick Fix
* [tgbot] Quick Fix 2
* [tgbot] Big Updates
Added Notifications for Clients throught Tgbot (when Expire)
Added compability for Usernames both w/wo @
Added more buttons overall for admins
* [tgbot] Fixes
* [tbot] Fixes 2
* [tgbot] Removed usernames support for Notifications to work
* [tgbot] Fix
* [tgbot] Fix Notify
* [tgbot] small fixes
* [tgbot] replyMarkup only for last message on big messages
* [tgbot] Fixed last message is empty
* [tgbot] Fix messages split
* IP Limit Tweaks to reduce false bans
1) Check IPs every 10s instead of 20s
2) F2B jail: maxretry 3 -> 4, findtime 100 -> 60
* USERS SHOULD UPDATE BANTIME ONCE AFTER UPDATE
to recreate jail for Ip Limit
after this
if limitip is 0 and there is no access.log on xray config you don't see this warning
access.log doesn't exist in your config.json
-------------
better view on ip log
-------------
update dependencies
* Logging for fail2ban service
Removed limitDevice and other unnecessary functions
* Logging for fail2ban service
Removed limitDevice and other unnecessary functions
* fixed shouldCleanLog
* last fix
* reduced ip limit detection frequency to 30 sec (less logging, more precise)
changed maxretry in fail2ban jail config to 2 to fit above
* fixed check delay
* added 5 seconds delay before cleaning logs
now only those IPs that are allowed are able to establish a connection; other connections are dropped it will happen every 10 sec
after user offline that IPs will be removed from AllowedIps
