refactor: cce-authenticator on routed events (6bd shrink — the tail is done)

The flat dialog dispatch — background, password box, verify/cancel/
fingerprint buttons, and the single-target keyboard delivery — routes one
Event per root through ui_context.propagate_event. The unfocus-on-missed-
press rule and the take_click drains stay. No chains, no composites, no
drags: the simplest conversion of the set, and the last one.

Verified live A/B under CCE_AUTH_SIMULATE --standalone (the dialog stays up
in simulate, no 3s auto-exit as previously recorded): password-box focus
click byte-identical (AE=0); Cancel click closes the window in both builds
(0 windows after — the process lingers briefly in teardown, don't read
pgrep at +1s as a hang); static differs by one cursor sprite. Password
typing / Enter-verify / fingerprint flow: user spot-check.
