Polish Become a Member hero: full-bleed gradient, button sizing + interaction, remove tag pills

- Hero gradient now spans edge to edge (full-viewport ::before band behind the
  centred content) and is more colourful/on-brand (warm peach to soft teal).
- Both hero CTAs (Become a member / See what we do) share one size so they align.
- Add hover (lift + shadow + colour shift) and active (press) states to the
  reusable .btn classes, so all buttons site-wide get consistent feedback; plus
  a focus-visible outline for keyboard users.
- Remove the confusing Community/Events/Support/... tag pills (they duplicated
  the hero lead sentence). member.js updated + now emits main.js on the member
  pages so regeneration keeps the nav working.
