refactor(brand): adopt new primitives in admin + data + dialogs

The remaining per-file 2-4 line adjustments land here: the admin
cards (EmailNotifCard, UsersTable), the bank-sync section, and the
two cross-cutting dialogs (ReleaseNotesDialog, SearchFilterPanel)
adopt the same BrandGlyph / TonedCard / SectionHeading imports as
the rest of the app. Each file is independently buildable on top of
the previous 6 commits.

This is commit 7 of 9 in the v0.42.0 brand refresh. Depends on
0eb024d (pages).
