docs: remove incorrect watchPlugins: false references

Remove all references to the incorrect `config.watchPlugins: false`
requirement that was believed necessary for Headlamp v0.39.0+.

Investigation revealed that plugins work correctly with the default
`watchPlugins: true` setting. The earlier documentation was based on
a misunderstanding of the plugin loading mechanism.

Changes:
- Remove watchPlugins: false from all YAML configuration examples
- Remove warning sections about watchPlugins requirement
- Update troubleshooting guides to focus on actual issues
- Simplify installation instructions by removing unnecessary config

Files updated:
- README.md (main installation docs and troubleshooting table)
- docs/DEPLOYMENT.md
- docs/TROUBLESHOOTING.md
- docs/getting-started/* (quick-start, installation, prerequisites)
- docs/deployment/* (helm, production)
- docs/troubleshooting/* (common-issues, README)
- Multiple other doc files formatted by prettier

This cleanup ensures ArtifactHub and GitHub documentation show
correct, simplified installation instructions.

 ## Known Issues
 
-### Plugin Loading Issue (Headlamp v0.39.0+)
-
-**Symptom:** Plugin appears in Settings but not in sidebar
-
-**Cause:** `config.watchPlugins: true` (default) treats catalog plugins as development plugins
-
-**Fix:**
-
-```yaml
-config:
-  watchPlugins: false  # Required for plugin manager
-```
-
-**Root Cause:**
-
-With `watchPlugins: true`, Headlamp backend serves plugin metadata but frontend never executes the JavaScript. This causes plugins to appear in Settings but no sidebar/routes/settings work.
-
-**Documentation:** See `deployment/PLUGIN_LOADING_FIX.md` in repository for full analysis.
-
-**After Fix:**
-
-- Restart Headlamp deployment
-- Hard refresh browser (**Cmd+Shift+R** / **Ctrl+Shift+R**)
-
 ### Skipped Count Limitation
 
 **Symptom:** "Skipped" count in UI is lower than native Polaris dashboard
