refactor(career): Phase 1 increment 2 — extract editor sections, hide duplicate CV concepts

UI-only. No change to APIs, save payloads, extraction behaviour, or data
models. The parent CareerProfilePage still owns loading, state, saving,
and all extraction/import actions; the new sections are presentational
(value + onChange, plus a getMetadata callback for review chips).

Extracted into src/views/career/CareerProfileSections.tsx:
PersonalInformation, ProfessionalSummary, Skills, Interests, Languages,
WorkExperience, Education, OtherSections. FieldReviewNote + confidenceTone
moved there verbatim and shared with the parent. CareerProfilePage went
from 1376 to ~1200 lines.

No Projects/Certifications sections were created -- the editor never had
them (they are not editable structured fields here). Inventing them would
add functionality, which this refactor avoids; noted for a product
decision later.

Hid the duplicate CV concepts behind an "Advanced CV tools" toggle,
collapsed by default: the CV Structure Overview parse block and the
Template-driven CV builder. Both stay mounted and functional (gated with
display:none), so no tested functionality is removed -- the real CV
Builder at /career/builder is the single generation surface. Future
removal plan documented.

Tests: added "editing a field in an extracted section updates parent
state and flows into save" (render -> edit -> PUT /career/profile
{profile,cvText}); existing parse/rewrite tests reveal the advanced tools
first. The increment-1 save-invariant test still pins the payload.

Verified: tsc clean, production build clean, 137 frontend tests pass.
Backend untouched.

-**Remaining in Phase 1 (staged, needs the app running to click-verify each section's save

-- Extract the editing sections into `PersonalInformationSection … LanguagesSection` components and a

-  (so behaviour stays identical). This is voluminous mechanical JSX movement through a 1376-line file.
-- Hide the **template-driven CV builder** (rewrite templates + PDF carousel) and the **structure

-  each removal must move its test coverage, not delete it — done incrementally with verification.
-- Per-section actionable empty states ("No work experience added yet" → [Add experience]); the Add

+*Sections extracted* into `src/views/career/CareerProfileSections.tsx` (one file, one component per
+export), plus `FieldReviewNote` + `confidenceTone` moved there verbatim and shared with the parent:
+
+| Component | Slice | Props |
+|---|---|---|
+| `PersonalInformationSection` | `contact` | `value`, `onChange`, `getMetadata` |
+| `ProfessionalSummarySection` | `summary` | `value`, `onChange`, `getMetadata` |
+| `SkillsSection` | `skills` | `value`, `onChange`, `getMetadata` |
+| `InterestsSection` | `interests` | `value`, `onChange`, `getMetadata` |
+| `LanguagesSection` | `languages` | `value`, `onChange`, `getMetadata` |
+| `WorkExperienceSection` | `jobs` | `value`, `onChange` |
+| `EducationSection` | `education` | `value`, `onChange` |
+| `OtherSectionsSection` | `otherSections` | `value`, `onChange` |
+
+Each section is presentational: it receives its slice + `onChange(next)`; the parent still holds
+`structuredCv`, loads, saves, and owns every extraction/import action. `getMetadata` is a callback
+(`getStructuredCvFieldMetadata` over the whole profile) so sections stay decoupled from the full shape.
+No section makes an API call. `CareerProfilePage` dropped from 1376 → ~1200 lines.
+
+**No `ProjectsSection` / `CertificationsSection` were created** — the editor never had those sections
+(`StructuredCvProfile` has no editable projects/certifications UI here; such content lives in "Other
+sections"). Inventing them would add functionality, which this refactor explicitly avoids. Flagged for
+a product decision in a later phase.
+
+*Duplicate concepts hidden* (not deleted) behind an **"Advanced CV tools"** toggle on the Career
+Profile page, collapsed by default:
+- **CV Structure Overview** ("Profile sections" parse block)
+- **Template-driven CV Builder** (rewrite templates + PDF carousel)
+
+Both stay mounted and fully functional — gated with `display: none` via `showAdvancedCvTools`, so the
+underlying flows (and their tests) are intact and reachable, just out of the default workflow. The
+real CV Builder at `/career/builder` is the single CV-generation surface.
+
+*Tests* (all green): existing profile-page tests re-pointed to reveal advanced tools before touching
+those controls; added "editing a field in an extracted section updates parent state and flows into
+save" (proves render → edit → `PUT /career/profile { profile, cvText }`). The save-invariant test from
+increment 1 still pins the exact payload.
+
+*Verified:* tsc clean, production build clean, **137 frontend tests pass**. No API, save-payload,
+extraction, or data-model change.
+
+**Future removal plan (later phase, not now):** once Phase 2 (Import CV review) and the real CV
+Builder cover every flow the hidden blocks serve, delete the structure-overview parse block and the
+template-driven builder from `CareerProfilePage` entirely, and drop the `showAdvancedCvTools` toggle.
+Until then they remain behind the toggle so no tested functionality is lost.
+
+**Still open for Phase 1 polish (optional, low priority):** a dedicated `CareerProfileHeader`
+component and per-section actionable empty-state copy ("No work experience added yet" → the Add button
+already present). Neither is blocking; both are cosmetic.
