feat(links): richer share-link labels across QR, client info and sub views

Show colored protocol/transport/security tags followed by the inbound remark and port for each share link in the client QR modal, client info modal and subscription page. The client email and the traffic/expiry decorations are stripped from the remark so only the inbound remark and port remain.

Consolidate the duplicated per-page parseLinkMeta/trimEmail/PROTOCOL_COLORS into a shared lib/xray/link-label.tsx (parseLinkParts, LinkTags, linkMetaText) so the colours and the email/stats stripping stay identical across all three surfaces.
