feat(website): tier-driven progressive partner margin calculator

The /partners margin calculator now derives margin from the user count using
progressive brackets (like tax brackets): first 500 users at 15%, 501–1000 at
30%, 1001+ at 40%, off the 49 kr/user/mo list price. Replaces the manual margin
slider with a live per-bracket breakdown. Rates are read from the tier copy;
tier thresholds aligned to 501 / 1.001 so the cards and calculator agree.
