Sync profile with updated resume (Aug 2026)

Source: updated resume PDF supplied by Sajeeb.

- Point the "Download resume" button at the new Drive file; the old link
  (1mG9AKfa...) is superseded.
- Display name becomes "Mohamed Sajib (Sajeeb Ahmed)" so the site matches
  the resume while staying recognisable against the domain, GitHub handle
  and email, which all use the Sajeeb Ahmed form.
- Populate `certificates`, which was an empty array: Full Stack Web
  Development (Programming Hero, 2021) and JavaScript Certification
  (freeCodeCamp, 2020). The Certificates panel renders automatically now
  that the list is non-empty.
- Add skills listed on the resume but absent from the site: TypeScript,
  Sass, Bootstrap 5, Vite, Vercel, Firebase, VS Code, Prompt Engineering.
  TypeScript was a notable omission -- this site is written in it.
- Add a Design Tools group (Figma, Canva, Adobe Express, Sketch,
  VistaCreate); move Figma there from Tools & DevOps.
- Add phone to SocialLinks and render it as a tel: link in the contact
  card; narrow location to Tejgaon, Dhaka, Bangladesh.
- Update title, description, author and OG/Twitter tags for the new name.

Deliberately NOT taken from the resume, per Sajeeb:
- The resume omits the current Harrington (Blitzkrieg Group) role; the
  site is more current, so the entry and headline stay.
- The resume dates the Economics bachelor 2016-2017; 2017-2021 is
  correct and stays.
