feat: introduce CV variant schema, dual-written from tailored CV saves

Browse Source 
Phase F2 of the Career Workspace roadmap: CvVariant, CvVersion, and
TailoredApplication -- the reference seam. Per the product boundary,
a job application REFERENCES a tailored output; it does not own it.
CvVariant is not job-owned: it survives job deletion (SetNull on its
optional CareerProfile link, not cascaded), can be reused across
applications, and carries its own append-only CvVersion history.
TailoredApplication is the join that links a variant to a job
(cascades with either side, since the link is meaningless without
both).

Rather than shipping empty tables with no consumer, this dual-writes
from both existing TailoredCvDraft save paths (SaveTailoredCvDraft,
UpsertGeneratedTailoredCvDraftAsync via GenerateTailoredCvDraft) --
same pattern as CareerProfile in Phase F1. TailoredCvDraft remains
authoritative for every existing read path; the sync is additive and
never blocks or fails a draft save.

2 new tests: variant/version/link created on first save, same variant
reused (not duplicated) with version incrementing on subsequent
saves. Verified against the real dev DB -- FK dependency ordering
(CareerProfiles -> CvVariants -> CvVersions/TailoredApplications)
holds in both SQLite and MySQL reconciler dialects.
