feat(gallery): OR/exclude tag filtering — light chips + advanced builder (#6b/c/d)
Cluster A, milestone #97. Completes the frontend of the structured tag filter
(backend landed in 23fab98).

#6b store: gallery.filter gains tag_or (OR-groups) + tag_exclude; one model,
serialized via tag_or (repeated key) + tag_not across activeFilterParam/
filterToQuery/applyFilterFromQuery/cloneFilter/loadSimilar; _resolveLabels
resolves names for every referenced id. useApi now appends array param values
as a repeated key (tag_or=a&tag_or=b).

#6c light editor (GalleryFilterBar): autocomplete pick → include chip; click a
chip body to flip include↔exclude (exclude = red minus); ✕ removes. An
"N OR-groups" chip + an Advanced button open the builder.

#6d advanced editor (TagQueryBuilder.vue + common/TagPicker.vue): AND-of-OR
group builder + NOT list. Unifies includes+OR-groups into one groups view,
splits back to tag_ids/tag_or on Apply so the URL stays compact. Writes the
same model the light chips edit.

Store serialization round-trip tests added.
