Wavy-underline: allowlist to default; destroy-button and search polish

Flips the plain-link underline from an opt-in list (growing every time
a new context needed it) to the default a rule, with opt-outs living
as more specific overrides where something shouldn't look like plain
content -- .action_button, the icon nav, the search dropdown's bold
results. The allowlist's own history made the case for this: three of
its entries were already hand-copied duplicates of the same five
properties, and two of those had already silently drifted.

form.button_to's icon+text buttons (Destroy, currently) get the same
inline-flex/gap treatment .action_button already had -- they were
never included in that fix, so they still baseline-aligned an SVG
against text instead of centering it, plus an explicit icon size
they'd never had either.

Dashboard search results: tags render as a wrapped row of pills
instead of one-per-line, for visual distinction from page results.
The public-preview link and its Revoke button get their own row
rather than loose inline flow, which wrapped unpredictably next to a
long token URL -- aligned by box-top rather than center or baseline,
since a <button> doesn't reliably expose a text baseline the way a
plain link does, with a small compensating offset for the button's
own internal padding.
