Summary

Currently the TCP proxy for publicly exposed databases uses nginx’s default stream timeout (~10 min), which kills long-running queries. This adds a configurable public_port_timeout field so users can set their own timeout or disable it entirely.

/claim #7743

What changed

• Added public_port_timeout integer column (default 0) to all 8 standalone database tables
• Updated StartDatabaseProxy to inject proxy_timeout and proxy_connect_timeout into the nginx stream config
• When set to 0 (default), uses 604800s (7 days) - effectively no timeout
• Added the timeout input to all 8 database type UIs, next to the existing public port field

Testing

• Verified nginx config generates correct proxy_timeout directive
• Default behavior (0) maps to 7-day timeout to prevent idle disconnects
• Non-zero values pass through as-is in seconds
