fix(spec): regenerate stale api-surface snapshot after dead page-config removal (#2268) (#2272)

#2268 hard-removed 16 dead exports (6 from ./ui Blank/RecordReview, 10 from
./studio PageBuilder/Canvas/Palette) and #2265 added PAGE_TYPE_ROADMAP, but the
committed api-surface.json snapshot was never regenerated — so check:api-surface
has been red on main for every PR touching packages/spec/** (surfaced on #2269).

Regenerate the snapshot to match the built surface. Diff is exactly the 16
intentional removals + PAGE_TYPE_ROADMAP; api-surface-signatures.json unchanged;
the frozen downstream-contract gate is unaffected (it never referenced these
symbols).

Kept at minor (not a major bump) as a deliberate, documented exception to the
ADR-0059 §4 freeze contract — see the appended note in the #2268 changeset. The
removed symbols are config for renderless page types with no plausible
functional consumer; the pre-publish hotcrm live gate guards any real break.
