perf(insights): wire six sibling status routes to the shared timeout-stub helper

Bring blood-pressure, weight, general, pulse, mood, and
medication-compliance into parity with bmi-status. On a 20 s
provider stall every route now persists a sentinel auditLog row
keyed to today's Berlin day so the next mount short-circuits at
the cache lookup instead of re-racing the same provider call on
every cold visit. Eliminates the ~14 s warm response on every
dashboard open after a one-off provider hiccup.

The seven routes share one persist path through
`persistTimeoutStubAndReturn`; ~120 LOC of duplicate
`auditLog.create` calls collapse into the helper.

medication-compliance returns a richer `{summary, medications}`
envelope rather than the standard `{text}` shape, so it calls
the helper for the persist side-effect and maps `summary` ←
`text` on the way out. Its cache-read also gains a stub-row
recogniser so the second-mount short-circuit fires on the
helper's `text` + `timeout: true` payload.

Tests cover both arms per route: the persist-on-timeout path
asserts a single auditLog.create with `timeout: true`, model
`timeout-stub`, and today's Berlin dateKey; the
short-circuit-on-stub path asserts a subsequent mount returns
the cached stub text without invoking the provider.
