Drop family framing from anki-progress; add anki-deck-*.py tools

anki-progress.sh and its embedded app.py assumed a family/kids use case
(dashboard title, ntfy topic default, Authelia warning text, comments)
that was never actually stated — nothing in this repo should assume who
the accounts belong to. Retitled to plain "Anki Progress" throughout,
default ntfy topic changed from family-anki to anki-progress, and every
"family member" reference reworded to "account".

Also adds tools/anki-deck-math.py, tools/anki-deck-periodic.py, and
tools/anki-deck-visual.py — the Anki deck-generation scripts developed
earlier in this session, now committed as standalone, self-documented
tools (same tools/*.{sh,py} convention as tools/dedupe-finder.py) rather
than living only in chat. Each script's own header docstring carries the
full one-time setup (venv, genanki + piper-tts, downloading a voice) and
usage — anki-deck-periodic.py and anki-deck-visual.py point back to
anki-deck-math.py's copy rather than repeating it three times. Content is
generic (multiplication/division/addition/subtraction/fractions/decimals,
the periodic table, shapes/clocks/coin-counting) — nothing here assumes
who's using it or why.

Re-verified after the rename: the embedded app.py still passes its full
logic test suite once written out by the installer, and all three
tools/anki-deck-*.py scripts still build correct decks under
--dry-run-tts after their docstrings were rewritten.

Adds a README.md section pointing at the three scripts, and updates the
anki-progress Services table entry to drop "family" from its wording.
