fix(analytics): mask session replays by default, chrome-only unmask (#1639)

* fix(analytics): mask session replays by default, chrome-only unmask

Invert PostHog session-replay masking from visible-by-default with pattern
masking to deny-by-default: every input value is masked wholesale (rrweb
maskAllInputs, no maskInputFn) and every text node is masked unless it sits
under data-ph-unmask chrome or a table column header (th). Chrome tags live
on the shared UI primitives (PageHeader, Label, Button except combobox
triggers, TabsTrigger, Badge, Card/Dialog/Sheet titles, tooltips, help
popovers, empty states, settings labels), and tagged chrome is still
pattern-scrubbed for amounts and person-/organisationsnummer. data-ph-mask
beats data-ph-unmask, so call sites that interpolate user data into chrome
stay masked; a very-thorough audit swept every unmasked primitive and each
found site got a call-site mask. Confirm-dialog wrappers and toasts stay
masked centrally: their copy describes user objects by design. Untagged new
UI over-masks instead of leaking. Privacy policy, RoPA and decision log
updated in the same change.

* fix(analytics): tag detail-section chrome merged from main

The register-detail primitives landed on main after the replay-masking
audit ran: kickers and DefRow labels are static i18n chrome, values stay
masked.

* fix(analytics): close skeptic and review findings on replay masking

Explicit data-ph tags now resolve before the th chrome fallback, so a th
nested inside a data-ph-mask container masks correctly (regression test
added). Seven missed text-leak sites get call-site masks: delete-invoice
and credit-page invoice numbers, IB-correction voucher reference, TIC
orgnr (served unnormalized, so the separator-based scrub cannot be relied
on), articles search-term empty state, dimension segment labels, and
activate-account buttons. The attribute channel is closed with rrweb's
blockClass: inputs whose placeholder carries an effective user value
(salary overrides, correction description, danger-zone confirms, credit
confirm) get ph-no-capture, removing the element from recordings while
the prefill UX stays intact; the pivot-th title attribute is dropped.
Privacy-policy effective date bumped to 2026-08-17.
