Task 11: Build CoreSkills tile ("Repeat Medications")

Created CoreSkillsTile component that presents skills as medications
with frequency dosing metaphor:
- Half-width card with amber dot header "REPEAT MEDICATIONS"
- 5 skill items with teal icon containers (lucide-react icons)
- Each item shows: skill name, frequency (e.g., "Twice daily"),
  start year, years of experience, and "Active" status badge
- Uses medication metaphor: "Data Analysis · Twice daily · Since
  2016 · 9 yrs"
- Data from src/data/skills.ts with user-specified frequencies
- Styled to match GP System concept with 6px radius items on
  dashboard background (#F0F5F4)
- Integrated into DashboardLayout in right column next to
  LatestResultsTile
