status; show 'Active — sshd, apache-auth' badge labels; FilterDetail sub-
component with source_file/override badges, FilterForm, Assign button, raw
config section
- New AssignFilterDialog: selects jail from enabled-jails list, calls
POST /config/jails/{name}/filter with optional fail2ban reload
- New CreateFilterDialog: name+failregex+ignoreregex form, calls
POST /config/filters, closes and selects new filter on success
- Extend ConfigListDetail: add listHeader (for Create button) and
itemBadgeLabel (for custom badge text) optional props
- Fix updateFilterFile bug: was PUT /config/filters/{name} (structured
endpoint), now correctly PUT /config/filters/{name}/raw
- Fix createFilterFile bug: was POST /config/filters, now POST /config/filters/raw
