* Env var - PAGE_WATCH_LIMIT enhancements
* Rebuild API docs
* Bump APi doc version
* test: cover PAGE_WATCH_LIMIT across every add path
- API create returns 429; API import returns 429 and refuses the batch whole
- quick-add and the UI importer flash the limit (importer once per file, not per row)
and hand unimported URLs back
- clone at the limit no longer KeyErrors
- an instance already over the limit still loads from disk and stays editable, only
new watches are refused
- the Info tab shows the limit only when one is set
- add_watch() with no request context returns None instead of raising from flash()
- an absent, empty or unparseable env var all mean unlimited
