fix: increase max socket.io message size to 10MB for large pastes (#7474)

* fix: increase max socket.io message size to 10MB for large pastes

The default maxHttpBufferSize of 50KB caused socket.io to drop
connections when pasting >10,000 characters. Increased to 10MB which
safely accommodates large paste operations.

Fixes #4951

* chore: reduce default maxHttpBufferSize to 1MB

10MB was too generous and creates a DoS vector. 1MB (socket.io's own
default) is sufficient for large pastes while limiting memory abuse.
