feat: add client column to aibridge_interceptions table (#21839)

Adds `client` column to `aibridge_interceptions` table. It is set accordingly to what is passed from AI Bridge in `RecordInterception`.
Adds interception filtering by `client` value.

Depends on: https://github.com/coder/aibridge/pull/158
Updates aibridge library to include this change.

Fixes: https://github.com/coder/aibridge/issues/31
