Add Privacy Policy and Terms of Service pages

Registration collects health-adjacent data (age, weight, height, health
notes, goals) with no privacy policy or ToS anywhere in the app. Adds
both as real pages at /privacy and /terms, a site-wide footer linking to
them (the app had no footer at all outside the homepage), and a consent
line on the registration form. Both pages are marked as a starting draft
with bracketed placeholders for operator/jurisdiction details rather
than inventing legal claims the app can't back up.

Also removed the homepage's own footer, which duplicated the new global
one and whose Privacy/Terms/About/Contact links were all dead `#`
placeholders, and fixed APP_NAME (was "Laravel", site is branded
FitAtlas everywhere else including the browser tab title).
