fix: resolve tag via Immich API instead of local DB table in remove_tag

The local tag table can lag behind Immich's own tag state (e.g. tags
created directly in Immich, or before this app's sync ran), causing
remove_tag to silently no-op on a tag that actually exists. Mirror the
sibling "tag" action's approach and resolve against the Immich API,
matching on the tag's full-path "value" field. Drops the now-unused
db/sql local lookup.
