Marc-André Bombeck bec7538012 fix(workouts): enforce the numbers-only evidence claim in code
The projection's central claim was carried by a comment. It is now walked
before it is returned: any non-numeric leaf at any depth throws, and the only
two string leaves are allowlisted by shape — the sport type against the schema
enum itself, and the day key against its format.

This matters because sport_type is a TEXT column whose API write path is
enum-constrained but whose backup-restore path accepts any non-empty string, so
a restored row can carry arbitrary text. It is re-asserted at the projection
boundary rather than trusted from the column. The heart-rate provenance string
is dropped rather than allowlisted, and route geometry stays consumed-not-carried
— it yields one number, and location history may not ride a prompt.

Own-history rows now collapse cross-source twins through the canonical picker,
as the detail page's comparison already did; a session recorded by two paired
watches was inflating the sample size and biasing every median.
