feat(app): OpenFX UI wiring - effect library, inspector params, startup glue
- src/oakui/ofx.rs: startup sequence (host scan, register_plugin_nodes,
progress reporter factory -> app progress dialog channel, active
viewer time provider, project extent sync); all failures degrade to
logs. oak-worker runtime also scans and registers plugins.
- Effect library groups OpenFX entries by sub-category (Filter/
Generator/Transition/General); effect insertion goes through
Factory::create_any so dynamic plugin nodes resolve.
- Inspector renders OFX parameters from node inputs (sliders, combo
boxes from repeated combo_option/combo_value properties, vec/color
spinboxes, text with explicit commit, push buttons), edits are
undoable; persistent plugin messages surface as a card badge.
- oakplugin: push_button_clicked and per-instance persistent message
counting (thin public layers).
