Merge #42076: nested category plugin discovery + alias-normalized enable/disable (#41066)

Merge #42076: nested category plugin discovery + alias-normalized enable/disable (#41066)

Lands the complete nested category plugin fix:
- Discovery in `hermes plugins list` (from @islam666's #41076, carried in this PR)
- Alias-normalized enable/disable mutation path so nested plugins can be toggled
- Fixes the #41076 base breakages (web_server 6-tuple unpack + stale test fixtures)

Co-authored work: discovery by @islam666 (#41076).
Closes #41066.
