fix: remove Canvas pricing + legal monitors (they probed nonexistent paths)

Both monitors targeted www.moleculesai.app paths that have never
existed:

  - Canvas — pricing route → www/pricing → 404
  - Canvas — legal redirect → www/legal/terms → 404

The marketing site (www) serves /, nothing else. Legal pages actually
live on api.moleculesai.app/legal/{terms,privacy,dpa} and are already
monitored under "Control plane — Legal pages" (that probe turned
green after the earlier fly.dev → api.moleculesai.app repoint).

A real /pricing page doesn't exist yet — the TermsGate modal and
LowCreditsBanner both link to app.moleculesai.app/pricing which also
404s. Building it is tracked separately; until then, a stuck-red
probe helps nobody.

When pricing ships, re-add a targeted monitor pointed at the real URL.

Closes status issue #1 (pricing down) and #2 (legal redirect down).
