feat: make NIP-05 and image hash-verify symbols follow the accent

The NIP-05 identifier colour and its verified badge were a fixed purple, and
the image hash-verification "passed" seal was a fixed purple drawable — none
followed the selected accent. Redefine the nip05 token to the theme primary
(covering the identifier text, badge and the other nip05 call sites) and tint
the nip_05 and original drawables with the accent at render.

Also switch the hash-verification "failed" icon from a raw Color.Red to
colorScheme.error, matching the themed error red used everywhere else. Removes
the now-unused Nip05EmailColor light/dark constants.
