polish: configurator visual redesign + copy cleanup

- Redesigned progress bar: numbered circles with connectors, checkmarks on completion,
  line only fills up to current step, centered layout
- Redesigned service cards: horizontal 3-column grid, border-based selection state,
  check badges, staggered entrance animations
- Fixed card border clipping (ring → border)
- Fixed height stability (selection hint stays in DOM)
- Removed all em dashes, replaced with regular dashes
- Removed all Côte d'Azur / Riviera / France location references sitewide
- Philosophy quote attributed to "Matt Ciaccio, Founder"
- Footer: "American-founded. Serving clients worldwide."
- Email template: LetsBe Solutions LLC
- AI prompt: removed Côte d'Azur reference
