torlando-tech 9174d27183 Fix cross-thread race condition on BLE connection maps

send_outgoing() on loopTask (core 1) calls write() which reads
_connections, _clients, and _cached_rx_chars maps, while
processPendingDisconnects() on the BLE task (core 0) erases from
them — with no synchronization. This causes std::map red-black tree
corruption, manifesting as LoadProhibited crashes in map rotate/insert
operations (EXCVADDR=0x00000008).

Protect all map accesses in write(), writeCharacteristic(), read(),
enableNotifications(), getConnection(), getConnections(), and
processPendingDisconnects() with _conn_mutex. The mutex is released
before any blocking GATT operations (writeValue, readValue, subscribe)
to avoid holding it during 10-30s NimBLE timeouts.
