fix: P0/P1 bugs found by real endpoint testing

Two real production bugs surfaced while running end-to-end API tests:

1. extractCode regex P1: "Your verification code Your code is 824593"
   captured "Your" instead of "824593". The pattern's delimiter [:\s：\-]+
   allowed a single space, matching "verification code Your" greedily.
   Fix: reorder patterns to try numeric-first, require explicit colon or
   "is"/"为"/"是" as delimiter. Added 3 regression tests.

2. auth_tokens.status column missing in production P0: pause/resume
   failed with "status column may not exist". Root cause: schema.sql
   did not include status/scope/webhook_failures/webhook_status columns
   (they were only in migration files), and CI only ran schema.sql, not
   migrations. New table creations get the full schema; existing DBs
   need ALTER TABLE.
   Fix:
   - schema.sql: add all columns to CREATE TABLE (for fresh installs)
   - Add migration 0004-auth-webhook-columns.sql for webhook_failures
     and webhook_status
   - CI: run all migrations with "duplicate column name" tolerance
     (expected when ALTER runs against already-migrated DB)

Tests: 360 → 363 pass, 0 fail.
