## What
The transactions AI consent banner now lets users decline, tells them
the outcome, and stops appearing once they've decided.
- **Dismiss option**: an X button before "Enable AI" permanently hides
the banner without granting consent.
- **Show only until the first decision**: the choice is persisted on
`users.ai_consent_prompt_dismissed_at` (set on both accept and dismiss).
The banner shows only while the user hasn't responded and never
reappears afterwards — even if they later revoke consent from settings.
- **Clear feedback**: accepting or dismissing shows a toast stating
whether AI was enabled and that the choice can be changed anytime in
**Settings > Manage Plan**.
- **Full-width layout on desktop**: the banner content spans the full
available width (button pushed to the right, text on a single line). The
narrow stacked layout is kept for mobile only.
## How
- New `POST ai/consent/dismiss` endpoint
(`AiConsentController::dismiss`).
- `User::dismissAiConsentPrompt()` (idempotent) +
`hasDismissedAiConsentPrompt()`; `store` now also marks the prompt
dismissed on accept.
- Migration adds the nullable `ai_consent_prompt_dismissed_at`
timestamp.
- `TransactionController` passes `aiConsentPromptDismissed` to the page.
## Tests
- `AiConsentTest`: idempotent dismissal, dismissal without consent, and
accept marking the prompt dismissed.
- Full consent + backfill suite and the `create a transaction` browser
test pass; pint / lint / format clean.
Suggests transaction categorization rules during onboarding.
After a sync or import, it groups the uncategorized transactions, asks
Gemini (via laravel/ai) to map the common merchants to categories, and
shows the results for review. The user edits or drops any and creates
the ones they want. During onboarding the accepted rules also categorize
existing transactions right away.
Off by default: it needs the `AiRuleSuggestions` Pennant flag and a
per-user AI consent. The model and thresholds are config-driven.
`ai:suggest-rules {user}` prints what a user would get.
The settings-page surface and monthly regeneration are a follow-up.
