Birthday Reminders — email relatives their upcoming-birthday digest, with each person's relationship to them

[jbh4x82]

Sharing another small module, in case it's useful to others.

Birthday Reminders emails each subscriber a personalised digest of the upcoming birthdays among their relatives — and every birthday is annotated with how that person is related to the subscriber (e.g. "daughter", "first cousin"), resolved with webtrees' relationship engine.

Highlights:

• Daily digest by email, localised to each subscriber's own webtrees language (English, German, French, Italian, Spanish shipped).
• Distance filter — each subscriber chooses how closely related someone must be to appear — plus follow specific people by name, whose birthdays then always appear regardless of the distance cap.
• Individual-page panel (via ModuleSidebarInterface) showing the viewer's relationship to that person, with a one-click "remind me of this birthday" toggle.
• Self-service settings with a sensible auto-subscribe (never clobbering an existing subscriber's preferences).
• Self-creating tables; a token-guarded cron route with a dry-run mode and a single-subscriber digest preview.

GPL-3.0-or-later, webtrees 2.2.x (PHP 8). It pairs nicely with the Famous Family Members module I shared earlier.
