fix: resolve health check issues with Redis and du commands

Fixed multiple issues in health check script:

1. Redis check failing due to missing .env loading
   - Re-added .env sourcing at script start
   - Redis container doesn't have REDIS_HOST_PASSWORD in env
   - Script needs to load it from .env file

2. Script exiting early when du returns non-zero exit code
   - du returns error code 1 when it can't read some subdirectories (permissions)
   - Even though it outputs the size successfully
   - Added || echo "" to handle non-zero exit codes gracefully
   - Fixed for DATA_SIZE, DB_SIZE, and LOGS_SIZE checks

3. Fixed typo in DB_SIZE validation (was checking DATA_SIZE instead)

These fixes ensure:
- Complete health check output with summary section
- No premature script exits
- Proper Redis authentication testing
- Robust handling of permission errors in du commands
