Merge claude/2

The location editor's Type, Path Mode, Engine and SSH Auth selects rendered
with no options. The config generator only scans flat per-category files and
never descends into configs/backup/locations/<n>/, so configData carries no
options for CFG_BACKUP_LOC_<n>_* keys — and the hardcoded fallbacks had been
removed in favour of generator-emitted ones.

Resolve these four dropdowns by suffix in ConfigOptions.getSelectOptions with
their static option lists (labels mirror location.config), so every location
works regardless of index — including locations added after install. The
global CFG_BACKUP_ENGINE/STRATEGY selects still come from the generator.
