…watchd

Rename all full .htaccess caching directive references from
MaxCacheHTCache* to MaxCacheHtaccess* to match the 1.1.0 module
renaming. Also updates:

- Config file path: maxcache_htcache.conf → maxcache_htaccess.conf
- Status handler: htcache-status → maxcache-htaccess-status
- Status page title: mod_maxcache HTCache Status → MaxCache Htaccess Caching Status
- Log prefixes: htcache: → maxcache-htaccess:
- RevalidateInterval default: 60 → 0 (check every request)

Removes all references to the maxcache-htcache-watchd daemon which
was removed in MAXWS-1043. Change detection now uses per-request
stat() polling only. Updates:

- Installation command (removed maxcache-htcache-watchd package)
- Package table (removed watchd row)
- Change detection section (replaced watchd/fanotify with stat() polling)
- Status page example (removed Invalidation SHM line)
- Troubleshooting table (removed watchd/SHM checks, added module/config checks)

Adds a "Changes in 1.1.0" note documenting all renames, watchd
removal, and backward compatibility behavior.
