## What & why
Fixes the Sentry N+1 **PHP-LARAVEL-3V** — `N+1 insert into jobs` on
`POST /transactions`.
### Root cause
Laravel's **event discovery is on by default** (the base
`EventServiceProvider` sets `$shouldDiscoverEvents = true`, and this app
has no subclass to turn it off), so every listener in `app/Listeners` is
already wired to its event by its `handle()` type-hint.
`AppServiceProvider::boot()` was **also** registering six of them with
`Event::listen(...)`, so each ended up registered **twice** — every
queued listener published its job twice per event.
Concretely, creating a transaction dispatched
`AssignTransactionToBudget` and `CategorizeTransactionWithAi` twice each
→ repeated `insert into jobs` in one request. (The same bug made
`PostStripeEventToDiscord` post to Discord twice per webhook,
`ApplyAutomationRules` run twice, etc.)
## Changes
1. **`AppServiceProvider`** — drop the redundant explicit
`Event::listen` calls and rely on discovery, which already wires every
listener exactly once (`ScheduleDripEmailsListener` and
`SyncUserToResendListener` were discovery-only already). Verified with
`php artisan event:list`: each event now has a single listener, and the
synchronous `ApplyAutomationRules` still runs first on
`TransactionCreated`.
2. **`CategorizeTransactionWithAi`** — add `shouldQueue()` so the job
isn't even published when it would immediately no-op (already
categorized by a rule, encrypted, or user not AI-eligible — the default,
since AI is opt-in). The same guard still runs in `handle()` because
state can change while the job waits.
Together these remove the second `insert into jobs` on transaction
creation for the common (non-AI) path.
## Tests
- New `tests/Feature/Ai/CategorizeTransactionWithAiListenerTest.php`:
the AI job is queued **once** for an eligible uncategorized transaction,
and **not at all** when the user has no AI consent or the transaction is
already categorized.
- Full suite: **1828 passing**. The one failure (`DashboardTest` → 409)
is **pre-existing on `main`** (Inertia asset-version mismatch from a
local build manifest) and reproduces with these changes reverted —
unrelated to this PR.
