Move Composio, logo.dev and Antigravity keys into Settings

The three third-party keys were hardcoded or read from the environment.
Operators now enter them in Settings > Integrations; they are stored
encrypted in the app-wide integration_keys table (migration 058).
An agent holding connector grants fails loudly when no Composio key is
saved. The goal-review test no longer depends on absolute dates.
