test(playwright): repair 14 selector-drift failures from two Central UI refactors

All 14 pre-existing Playwright failures triage to selector drift, not rig data,
timing, or application defects — every one is a test-side assumption that two
merged UI refactors invalidated without updating this suite.

`9e243493` (2026-08-11 density sweep + Theme 0.4.1) regrouped page/dialog action
buttons into `btn-group btn-group-sm`, moving the size class off the button and
onto the group. Twelve selectors still pinned `.btn-sm` on the button itself:
ConfigurationAuditLog's Search (4 tests), the Topology Create/Move dialog footers
(3), the Notification Lists row Edit/Delete (2), and the Notification Report row
Retry/Discard (2). The same sweep re-cast SiteForm's per-node subsections from
bare `<h6>` headings to Bootstrap cards, so `h6:has-text('Node A')` matches
nothing (1). Note the swept surfaces are a subset — the recipient table on the
notification-list edit form, OffsetPager, DiffDialog and friends still carry
`.btn-sm` on the button, so the selectors are deliberately asymmetric; the
remaining `.btn-sm` selectors in this suite were each re-verified against current
markup rather than swept along.

`a506b19d` moved TemplateEdit's page-embedded modals onto the DialogService host.
The attribute modal is now the DialogHost modal (`modal fade show d-block`, title
in an h5), so the `:not(.fade)` guard written to exclude DialogHost — plus the
`h6.modal-title` assertion — excluded the very modal under test (2). TemplateEdit
renders no page-local modal any more, so the guard has nothing left to guard.

Comments at each site record why the size class is absent, so a future reader
does not "fix" the selectors back.

Verified: 14 failed / 158 passed baseline -> the 36 tests in the seven affected
classes all green; solution build 0 warnings / 0 errors.
