feat(ui): broaden footer CTA from "Contact FLUX Engineering" to "Contact FLUX Team"

"Engineering" framed the CTA as technical-only and could deter non-technical
visitors (pricing, general questions, partnerships) from reaching out.

- Button label: "Contact FLUX Engineering" -> "Contact FLUX Team"
- AI trigger prompt broadened to invite any enquiry (energy savings, custom
  solution, pricing, availability, or just learning more), not only a
  technical consultation.
- DEFAULT_FOOTER ctaSubtitle softened to "Connect with our team to calculate
  your ROI, explore solutions, or simply ask a question." (the live footer
  can still override this from Site Settings in the HQ).
