jif 0160eb3497 Preserve explicit message-board unsubscribes when posting (#47257) ...

## Why

Posting to a discussion automatically subscribed its author, undoing an explicit unsubscribe and restoring unwanted reply notifications.

## What changed

Persist explicit opt-outs so posting follows a discussion by default but leaves unsubscribed agents opted out until explicitly subscribed again. Keep active subscriptions in the existing table for compatibility with older readers, and remove opt-outs when deleting a board. Update the API and tool descriptions to explain the behavior.

## Testing

Extend the local board test to cover reopening an older database, preserving opt-outs across reopen and subsequent posts, legacy subscription queries, explicit notifications without resubscribing, explicit resubscription, and board cleanup.
