refactor(career): Phase 1 increment — user-facing terminology + component split

UI-only restructuring of the Career Profile surface. No change to
database models, CareerProfiles schema, CvVariants, extraction APIs, AI
services, CV rendering, or public CV.

Terminology -> user-facing (i18n strings):
- "Structured CV editor"     -> "Career information"
- "CV structure overview"    -> "Profile sections"
- "Summary bullets"          -> "Professional summary"
- "Core skills"              -> "Skills"
- "Analyze sections"         -> "Read sections"
- "Original extraction"      -> "Original import"
- hardcoded "Master career profile" -> "Career profile"
Help text de-jargoned; the Career information help now frames it as the
source the CV Builder consumes.

Component split (first step): extract ProfileCompleteness (completeness
meter + missing chips + version history) into src/views/career/. Display
only, props in, no state or API.

Save path untouched: api.put("/career/profile", { profile, cvText }). A
new test pins that exact call as the refactor invariant so the remaining
section extraction cannot silently change save behaviour. Existing
profile-page tests re-pointed to the new labels; every behavioural
assertion (save, parse, field values) kept.

Verified: tsc clean, production build clean, 136 frontend tests pass
(135 + 1 invariant). Sidebar fix from the previous task still passes.
Backend untouched.

The remaining Phase 1 work (per-section editor components, hiding the
template-driven builder and structure-overview blocks, actionable
per-section empty states) is staged in docs/career-workspace-ux-refactor.md
because it touches the live extraction test surface and is best verified
by driving the authenticated UI. This increment is a clean, non-regressing
checkpoint.
