fix: filter requests by hostname instead of path

[manalkaff]

Summary

• The search filter on the Requests tab was matching against RequestPath (the URL path) instead of RequestHost (the hostname)
• Updated parseRawConfig in packages/server/src/utils/access-log/utils.ts to filter by log.RequestHost
• Updated the input placeholder from "Filter by name..." to "Filter by hostname..." to accurately reflect what is being filtered

Test plan

• Go to the Requests tab in Dokploy
• Type a hostname (e.g. myapp.example.com) in the filter input — results should filter by hostname now
• Verify that typing a URL path (e.g. /dashboard) no longer matches unrelated hostnames

Fixes #4249

Greptile Summary

This PR fixes a bug where the search filter on the Requests tab was incorrectly matching against RequestPath (the URL path) instead of RequestHost (the hostname). The server-side filter in parseRawConfig is updated to use log.RequestHost, and the UI input placeholder is updated from "Filter by name..." to "Filter by hostname..." to match.

Confidence Score: 5/5

Safe to merge — a one-line targeted bug fix with no side effects.

RequestHost is confirmed as a valid field in the LogEntry type, the change is minimal and correct, and the placeholder update accurately reflects the new behavior.

No files require special attention.
