chore: rename the project to Privacy: Period Tracker

"Period" was always a working name — PRODUCT_PLAN.md §55 said so. The real
identity arrived with the brand guide and artwork, and this makes the project
call itself by it.

The repository is renamed in place on Forgejo (null/Period ->
null/Privacy-Period-Tracker), which keeps all 30 commits, all 27 issues, all 8
milestones and the four severity labels — verified by counting them on both
sides rather than assuming a rename is lossless. The git remote follows in the
same breath, so this commit's automatic push is what proves the new URL works.

WHAT DELIBERATELY DID NOT MOVE

"Period" is the product name AND the central domain word, and a mass rename
would have turned the data model into nonsense. PeriodRecord, PeriodWriteResult,
confirmPeriodStart, the period_records table and the button that says "Started
period" all describe a menstrual period rather than a product, and all 239
references to them are untouched.

So are the Kotlin package and applicationId. dev.privacyllc.period already reads
correctly under the new name — privacyllc is the company, period is the app —
and changing it would rewrite 68 files, rename the Room schema directory and
break the hardcoded path in schema-guard.sh for no gain. period.db stays for a
sharper reason: renaming a database file orphans the data on every device that
already has it.

Sixteen files changed, and the diff is small on purpose.

THE NAME HAS A SPACE AND THE ARTWORK DOES NOT

Canonical is "Privacy: Period Tracker". The supplied wordmark sets it without
one, so logo.webp and banner.webp now disagree with every document and with the
app itself. BRAND_GUIDE.md §10 is updated to the space form and says plainly
that the drawn mark has not caught up. Filed separately rather than papered
over, because closing that gap needs an artist and not a rename.
