feat(connections): run a logic function on connection provider connect (#23167)

## What

Adds an optional `onConnectLogicFunctionUniversalIdentifier` field to
the connection provider manifest. When set, the referenced logic
function is dispatched right after an OAuth connection is successfully
established for that provider.

This gives apps a first-class "on connect" hook — e.g. the Slack app can
resolve the workspace's `team_id` via `auth.test` and claim the `team_id
-> workspaceId` mapping in the SERVER key-value store immediately on
connect, instead of racing against later events.

Follow-up to the app key-value store PR (#23089).

## How

- **twenty-shared**: add `onConnectLogicFunctionUniversalIdentifier` to
`ConnectionProviderManifest`.
- **twenty-sdk**: expose the field in `defineConnectionProvider` and
validate it is a UUID `universalIdentifier`.
- **twenty-server**:
- add a nullable `onConnectLogicFunctionUniversalIdentifier` column to
`ConnectionProviderEntity` (+ fast instance command / migration).
  - map the field through the
