jpetree331 ec0d880036 fix(database): B-1 schema integrity and migration fixes
- Fix migration 024 self-insert and bad column reference (F-B1-1, F-B1-2)
  Uses existing enabled/auto_run columns instead of non-existent deprecated
- Abort server on migration failure instead of warning (F-B1-11)
  main.go now calls log.Fatalf, prints [INFO] only on success
- Fix migration 018 scanner_config filename suffix (F-B1-3)
  Renumbered to 027 with .up.sql suffix
- Remove GRANT to non-existent role in scanner_config (F-B1-4)
- Resolve duplicate migration numbers 009 and 012 (F-B1-13)
  Renamed to 009b and 012b for unique lexical sorting
- Add IF NOT EXISTS to all non-idempotent migrations (F-B1-15)
  Fixed: 011, 012, 017, 023, 023a
- Replace N+1 dashboard stats loop with GetAllUpdateStats (F-B1-6)
  Single aggregate query replaces per-agent loop
- Add composite index on agent_commands(status, sent_at) (F-B1-5)
  New migration 028 with partial index for timeout service
- Add background refresh token cleanup goroutine (F-B1-10)
  24-hour ticker calls CleanupExpiredTokens
- ETHOS log format in migration runner (no emojis)

All 55 tests pass (41 server + 14 agent). No regressions.
See docs/B1_Fix_Implementation.md and DEV-025 through DEV-028.

-- Ensure proper UNIQUE constraint on machine_id for hardware fingerprint binding
-- This prevents config file copying attacks by validating hardware identity
-- NOTE: Migration 016 already added the machine_id column, this ensures proper unique constraint
-- Drop the old non-unique index if it exists
DROP INDEX IF EXISTS idx_agents_machine_id;
-- Create unique index to prevent duplicate machine IDs (allows multiple NULLs)
-- Note: CONCURRENTLY removed to allow transaction-based migration
CREATE UNIQUE INDEX IF NOT EXISTS idx_agents_machine_id_unique ON agents(machine_id) WHERE machine_id IS NOT NULL;
-- Add comment for documentation
COMMENT ON COLUMN agents.machine_id IS 'SHA-256 hash of hardware fingerprint (prevents agent impersonation via config copying)';
