fix(ux): close medium UX-audit findings across flows, IA, and onboarding

Coach deep-links now carry launch context in the URL instead of dropping it
at the route boundary: /coach reads ?scope= (validated against the closed
CoachScopeSource enum) and ?ask= to seed the drawer's own prefill/scope
props, the Today check-in's "Adjust" action seeds ?ask= with the plan's own
words instead of opening a blank chat, and the workout detail page scopes
its coach button to workouts.

IA: give the document vault a "View N lab values" link on LAB_RESULT-shaped
documents (the auto-stage/OCR-commit linkage existed server-side with no UI
surface); disambiguate the two "Recovery" pages (RECOVERY_SCORE anatomy vs
the composite wearable page) with a distinct label plus a two-way
cross-link; move the opt-in nutrients sync card from Source priority to
Integrations, where every other sync surface lives; rename the user-menu
theme switcher off "Appearance" (collides with the Settings hub) and the
Environment settings section to "Location & weather"; cross-link mood,
mental-wellbeing check-ins, and mood insights, which were three
unconnected islands.

Onboarding: the getting-started checklist's data-source/notifications rows
now gate their fetch on the same checklistRelevant condition the other rows
use, instead of only-while-onboarding — they used to be stuck undone
forever for anyone who finished the wizard with under 5 measurements; the
tour wrap-up no longer promises a replay affordance that was removed;
the wizard's Withings card shows a connected badge once the OAuth
round-trip lands instead of leaving the button looking untouched in the
tab it was opened from; the done screen and Modules hub get a quiet
cross-link; the sleep empty-state CTA reads "Connect a source" instead of
being pinned to one vendor.

All copy changes land across every locale; de.json reviewed for register.
