fix(doctor): copy button per path row, readable chain count, cased source kinds

- every daemon file row gets a copy-to-clipboard action next to
  view/open so terminal users can grab the raw path
- audit stat subtitle says 'n of m events verified' instead of the
  cryptic 'n/m chain'
- capability source-kind breakdown renders display names
  (Bundle/MCP/System) instead of raw lowercase wire tokens
