The initials badge and reset button hardcoded two independent
fallback literals -- a background (#ec4899 / #0ea5e9) and a text
colour (#ffffff) -- that were only ever chosen together for a club's
own colour via Club._content_color_for. #ffffff on #ec4899 or
#0ea5e9 actually contrasts worse than black by the same WCAG formula
the app already uses elsewhere (verified: 6.4:1 vs 3.3:1, and 7.6:1
vs 2.8:1). Added a contrast_color filter so the text colour is always
derived from whatever background hex is actually in play -- real
club colour or fallback alike -- instead of a second, independently
guessed literal that can silently drift out of sync with the first.

Confirmed Resend's /emails endpoint accepts an html field alongside
text. Claim-approved email now carries an HTML alternative with the
club's logo/colours; allauth's password-reset email is overridden
with the same treatment, falling back to RosterChief's own branding
outside a club context.
