test(e2e): expand Playwright coverage for UI regression protection

Grow the suite from 41 to 77 specs covering previously untested UI
surfaces: channels admin CRUD with QR codes and keyboard nav, node
detail adoption/tag editing with the role permission matrix, SPA 404
page, sortable tables with URL-synced sort state, pagination with
filter-preserving links, mobile viewport (hamburger nav, mobile cards,
sort select), anonymous/member auth gating, raw packet detail, and
empty states. Route cards now assert history chart, recent-match links
and owner profile links.

Supporting changes: purposeful data-testids on channels/node-detail/
pagination/sort headers (plus aria-sort) and mobile nav; seed_data adds
30 trace_data filler groups for pagination, channels at every
visibility tier incl. one disabled, and a pw-operator profile.
