Tobias GesellchenandClaude Sonnet 5 28de254f77 fix(datastore): add lock-spanning Mutate helpers for presets/recents/sources
GetX-then-SaveX call sites did an unguarded read-modify-write: two
concurrent callers could each read the same starting list, mutate
different entries, and the second writer's Save clobber the first's
update. This is exactly what dropped a preset during #614's rapid-fire
preset-programming repro (overlapping PUT .../preset/N requests).

Add MutatePresets/MutateRecents/MutateConfiguredSources, each holding a
single write lock across the whole read-mutate-write cycle, and switch
resolvePresetSource's auto-add-canonical-source path (the same race,
for sources) to use the new MutateConfiguredSources.

Part of the #614 follow-up; more call sites (UpdatePreset's own preset
write, recents, other sources writers) still need converting.
