refactor(events): dispatch() canonical, fire() shim; converge fork callsites (task 3.7)

[agissept]

Stacked on #42 (task 3.6). Framework-first convergence of Illuminate\Events\Dispatcher to the L13 shape.

What

• dispatch() is now canonical (body moved from fire()); fire() is a thin alias return $this->dispatch(...) — removed in L13 stock, so it dies at the Events swap. queue()/until()/flush() call dispatch() internally.
• 18 fork-internal event-dispatch callsites → ->dispatch() (View, Console, Log, Foundation, Database\Connection, Router, Cache\ClearCommand, Queue\Worker, Auth\Guard, Mail\Mailer, and Eloquent\Model) so those components survive the swap to illuminate/events v13 (stock has dispatch, not fire).
  • Hidden callsite caught: Eloquent\Model fires via dynamic $halt ? 'until' : 'fire' → $dispatcher->$method(...), invisible to a ->fire( grep. 'fire'→'dispatch'; until left as-is (present in stock).
• Left untouched: Command::fire() and Job::fire() — different methods owned by the Console/Queue tasks (the 4 remaining ->fire( in src).

Ratchet bug fix

ci/convergence-ratchet.sh count() ran grep -rEc … "$1" without --, so the four ->-prefixed patterns (event_fire, where_raw, eloquent_lists, pagination_getters) were parsed as grep options, errored, and silently counted 0 — a no-op guard. Added the -- and regenerated the baseline to grandfather the now-visible real residues: event_fire=4 (Command/Job), where_raw=1, eloquent_lists=6, pagination_getters=15. These now actually enforce.

Tests

Fork suite 1643 green (21 skipped). Mock expectations for the event dispatcher retargeted fire→dispatch (dispatcher mocks only; until mocks untouched); added testDispatchIsCanonicalAndFireDelegates (parity + halt).

Follow-up (separate)

App repo dicoding: sweep Event::fire()/->fire( → dispatch() + grep guard (facade is Psalm-blind, same approach as cache-ttl).
