Feature: Building the missing pieces (API, Webhooks, Dark Mode, & Admin UI)

[simon-msdos]

Hey,
I gave the agentic-inbox a spin tonight and realized it was missing the agentic part

What I've already built and tested:

The API: built the backend logic for programmatic sending (includes internal API key management and documentation for bypassing Zero Trust via Service Tokens.).

Webhook System:  receiving emails.

Admin UI & Dark Mode: Overhauled the admin section to handle API/Webhook management and added a native dark mode toggle.

I saw some of these were requested or hinted at in other issues, so I just knocked them all out in one go.
I've got the PR ready to roll whenever you guys are down to take a look. Let me know!

Update from local implementation/deploy:

Shipped in commit 316d395 (feat: add review queue foundation) and deployed to Cloudflare Workers.

Deployed URL: https://marginlevers-inbox.vince-3c5.workers.dev
Version ID: 66f4552a-1f31-4502-ade3-64588bf1e38d

What shipped:

• Added decision metadata fields on emails (priority, category, recommended_action, review_status, decision_reason, confidence, defer/review/analyzed timestamps).
• Added migration 16_add_decision_metadata plus review/defer/category indexes.
• Added review queue API: GET /api/v1/mailboxes/:mailboxId/review-queue.
• Added decision APIs: POST /emails/:id/decision and POST /emails/:id/defer.
• Added /mailbox/:mailboxId/review UI with sidebar navigation, open-count, Done, and Tomorrow defer actions.
• Hardened reply quote cleanup so outbound replies do not expose HTML/CSS or encoded preheader filler in quoted original messages.
• Added/updated regression tests for migrations and reply quote cleanup.

Verification before deploy:

• bun run test: 66 passed
• bun run typecheck: passed
• bun run build: passed during deploy
• bun audit: no vulnerabilities found

Remaining follow-up:

• Review route is a functional foundation, but not yet AI-classified. Existing emails default to unreviewed, so the queue may initially be broad.
• Add outbound preflight quality gate for send/reply paths if we want stronger guarantees around final HTML, headers, recipients, attachments, and AI-generated draft quality before delivery.
• Add AI analysis/classification to populate priority/category/recommended action automatically.
