feat(identity): open identity_unresolved decisions for resources with no candidates

no_match resources (and lookup failures after auto-review gives up) now
open a decision in the inbox with options to set a TMDB ID, pick a local
work, or dismiss; ambiguous decisions get the same manual options.
Resolve accepts identity {tmdb | mediaEntityId} and assigns with a manual
lock. The inbox option dialog collects the TMDB type/ID or searches local
works; the identity pool links each pending item to its inbox filter.
