feat(services): add keyword-focused service landing pages

Add five SEO landing pages under /services that reuse existing section
components (GuaranteeBand, InlineLeadForm) and a new prop-driven ServiceFaq:

- /services/custom-erp-development
- /services/university-erp
- /services/government-it-solutions-gem-vendor
- /services/police-management-system
- /services/react-native-app-development

Each page has 1,000+ words of specific copy, a real portfolio-backed case
study (IIT Patna, PSCL Bihar, Police MS, Pophealth), a comparison table /
stat block, a page-specific FAQ that feeds the FAQPage schema, and a CTA into
the existing inline lead form (/api/contact). Service + FAQ + BreadcrumbList
schema are passed into SEO.astro; the visible FAQ accordion does not duplicate
the JSON-LD. All company stats match the canonical site-wide set.

Wire the pages into navigation: deep-dive links from the /services detail
sections, a new "Solutions" group on the HTML sitemap, and entries in both the
dynamic sitemap.xml.ts and the served static public/sitemap.xml.
