Bulletin board: per-row manage (edit / re-broadcast / delete) + local Block

Add inline management to the board for the connected viewer:

- On your own flyers: Edit (links to /?edit=1#<naddr>, which the main client
  now honors by loading the flyer straight into the editor), Re-broadcast
  (re-sends the already-signed event to all relays — no signing), and Delete
  (replaceable tombstone + NIP-09, signed via the device key or NIP-07; a
  pasted-nsec connection is pointed to the editor where the key is available).
- On flyers from others: Block — a per-device blocklist of author pubkeys
  (voxvera_blocked_pubkeys) that always hides them, with a "Clear blocked"
  control. This is roadmap #1's local blocklist direction.

The board hides tombstoned flyers (newest-version-wins so a delete can't be
undone by an older copy). New non-sortable actions column; a board delete-
confirm modal; 12 new strings × 14 languages. Adds e2e for block (hide/persist/
clear), own-vs-other actions, and board delete (tombstone + NIP-09 published),
plus a ?edit=1 deep link. 234 e2e across all six engines; docs updated.
