A new per-tree Cleanup page (and cleanup_service + endpoints), each fix
preview-first per the propose-then-approve rule:
- Mark deceased by birth year: lists people born ≤ a cutoff (default 1930) not
already deceased; apply sets is_living=false for the ones you keep checked.
- Set sex from a source GEDCOM: upload the source .ged (it carries SEX); matches
by name and proposes sex only where it's missing — far more accurate than
guessing from first names. Review, then apply.
- Names that look broken: flags date-in-surname / date-in-given / no-surname /
packed given names, with inline editable given+surname; fix the checked ones.
No migration (uses existing columns). 55 backend tests pass (preview+apply for
all three); frontend builds.
