Add server-side event logging to this app using logs.so.

1. Send events by POSTing JSON to https://api.logs.so/v2/log with header
   Authorization: LOGS_SO_API_KEY (read from an environment variable — never
   hardcode it, never expose it to the browser).
   Body: { "project": "<WORKSPACE_ID>", "channel": "<channel>", "event": "<short title>",
           "description": "<details>", "user_id": "<user email/id if known>",
           "tags": { <relevant ids/amounts> } }

2. Create one small server-side helper (e.g. lib/logsso.ts) wrapping this call.
   It must never throw, never block the response (fire-and-forget), and no-op
   when LOGS_SO_API_KEY is unset.

3. Add logging at every business-critical moment — SERVER-SIDE ONLY:
   ✅ Successes → channel "revenue" or "signups": new signup, subscription started,
      payment received, key feature used.
   ❌ Failures — these matter most → channel "failures": every catch block in API
      routes and server actions, webhook handlers that fail or fail signature
      verification, declined payments, cron jobs that throw or don't complete,
      failed external API calls.

4. Prefix every event name with an emoji: 💰 revenue, ✅ success, ❌ failure, ⚠️ warning.

5. Never log secrets, passwords, tokens, or card numbers. Do include user
   email/id, amounts, and object ids in tags.

When done, list every file you changed and every event now tracked.

Note: Work through the whole repo: find existing catch blocks, webhook handlers, and cron jobs and instrument them.
