Overhaul site content to reflect custom networking solutions focus

Remove all ISP-subscriber framing (coverage areas, residential plans,
500+ customers, backbone capacity) and replace with accurate positioning
as a custom networking and managed services company.

Key changes:
- Hero: new headline and CTA focused on custom solutions
- Stats bar: Deployments, Uptime SLA, 24/7 support, response time
- Services cards: Mesh Networking, Managed Services, Access Control, IP Cameras
- Why section: founding story (tornado relief, tent deployment, charity event)
- CTA band: contact-focused instead of address lookup form
- Services page: expanded to 5 service areas with real content cards;
  removed Residential/Business internet sections
- About page: full founding story, mission statement, 4-step approach
- Portfolio page: repurposed from Coverage Map; shows deployment types
  including the disaster relief origin story
- Nav: Coverage → Portfolio, Get Connected → Request a Quote
- Footer: updated service links and tagline
- Router: coverage route renamed to portfolio
