cschantz 569f9947fd Fix critical logic issues in MySQL restore script
- Fix recovery level selection logic: Now uses error-type-based detection instead of
  level-based progression. Added detect_recovery_level_from_errors() function that
  maps specific error patterns to appropriate recovery levels (missing files → Level 1,
  redo incompatibility → Level 5, corruption → Levels 1/4/6 with escalation, etc.)

- Fix shutdown/reset crashes: Improved stop_second_instance() and cleanup_on_exit()
  trap handlers with proper validation. Now verifies socket removal and process
  termination before marking instance as stopped. Implements graceful shutdown with
  force-kill fallback if needed. Prevents stale sockets/locks that cause crashes
  on subsequent runs.

- Fix while loop condition: Removed buggy [ -n "$count" ] check that was always true.
  Loop now correctly terminates based on numeric condition [ "$count" -lt 30 ].

- Integrate error-based recovery recommendations: Modified show_recovery_options()
  to call detect_recovery_level_from_errors() early and display both error type
  and recommended recovery level to user. Provides intelligent, error-specific
  guidance instead of generic level progression.

All changes validated:
  ✓ Syntax check: bash -n passing
  ✓ QA scan: No new HIGH issues introduced (2 MEDIUM, 1 LOW are pre-existing)
  ✓ Script still handles all recovery scenarios
