- Fix wssshd2 last rate calculation to use data transferred since last status print instead of accumulated period

- Add missing start_time assignment in wsssht tunnel creation
- Update uptime display to show days-hours:minutes:seconds format

- Added format_bytes() function to display data sizes in B, kB, MB, or GB with 2 decimal places

- Updated all non-debug printf statements to use log_message() in wssshc.c and wssshd2/websocket.c

  to the correct endpoint regardless of sender (wssshc or wsssht)
- Fixed build warning by casting ws_state_t to int
- Added client registration/disconnection events in non-debug mode

Simplify ws_connection_is_healthy to avoid false positives from SSL_peek.
The complex SSL_peek-based health check was incorrectly marking healthy
connections as unhealthy, causing premature tunnel closures during
wsscp file transfers. Now uses simple state checks and relies on
send/receive operations to determine actual connection health.

- Add comprehensive thread-safety with mutex locks for all shared data structures
- Implement proper tunnel cleanup when websocket connections close to prevent use-after-free
- Add immediate connection state updates when receive operations fail to prevent race conditions
- Enhance error handling with graceful failure management for SSL operations
- Prevent server crashes during client disconnections and file transfer interruptions

Root cause: Use-after-free vulnerability when freed websocket connections were still referenced by active tunnels during client interruptions.

Solution: Complete overhaul of connection lifecycle management with proper synchronization and cleanup procedures.

Fixes issue where pressing Ctrl+C during wsscp file transfers caused wssshd2 to segfault.

- Add comprehensive error handling for pong frame transmission
- Improve SSL error diagnostics in ws_send_frame function
- Add connection state validation before sending frames
- Prevent sending frames on broken or NULL connections
- Better handling of SSL write failures with detailed error reporting
- Graceful degradation when pong frames fail to send
- Enhanced debugging for connection stability issues

The server now handles network interruptions and SSL timeouts more gracefully,
preventing premature connection closures during large file transfers.
