[DVOPS-382] Structure dependency wait script logs

[jesbinjoseph]

Summary

• add timestamped, leveled logging to the PostgreSQL and Redis wait scripts
• send waiting and availability messages to stdout
• keep exhausted-retry failures on stderr

Validation

• validated both scripts with bash -n
• checked both scripts with ShellCheck when available

Summary by CodeRabbit

• Improvements
  • Improved database and cache startup logs with timestamps and script labels.
  • Clarified retry, waiting, failure, and success messages for easier troubleshooting.
  • Distinguished informational messages from errors through appropriate output channels.

📝 Walkthrough

Walkthrough

The PostgreSQL and Redis wait scripts add timestamped, script-prefixed logging helpers. Retry-loop messages now use informational or error output while preserving retry behavior.

Changes

Startup script logging

Layer / File(s)	Summary
Timestamped logging helpers scripts/wait_for_db.sh, scripts/wait_for_redis.sh	Both scripts define log_info and log_error helpers with timestamped, script-prefixed output.
Retry-loop logging integration scripts/wait_for_db.sh, scripts/wait_for_redis.sh	Retry messages use the new helpers. Retry counting, delays, and exit behavior remain unchanged. Redis success messages now use stdout.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 54b1a

PostgreSQL and Redis dependency waits now emit timestamped, leveled logs with normal progress on stdout and exhausted retries on stderr. Retry behavior is unchanged, and no current merge-blocking risk remains.
