feat(ui): Logs color highlight based on log level

[ShadowArcanist]

Proxy Logs:

Current Dark Mode	New Dark Mode
Current Light Mode	New Light Mode

Application Logs:

Current Dark Mode	New Dark Mode
Current Light Mode	New Light Mode

How this works:

• We check keywords on logs like "err", "error", "wrn", "warn", and so on, then apply color based on the log type
• The log color shows based on precedence like Error > Warning > Debug > Info -- which means if a log contain both Error and warning keywords then it will show the log in Red color (Error) since Error have higher precedence

Colors:

• ERROR - Red
• WARNING - Yellow
• DEBUG - Purple
• INFO - Blue

Notes:

• I disabled "show timestamp" by default for proxy logs because traefik logs and most applications already include timestamp so having "show timestamp" enabled shows timestamp twice on the logs. Users can manually enable the "show timestamp" option if their app won't show timestamps on logs 😄
• I don't know PHP so all the changes are done by AI, but fully tested the changes locally (with both Traefik and Caddy) and it's working without any issues.
