feat(settings): split targets and sources, rename AI Insights section

Three related settings changes:

- Split the combined Targets & Sources page back into two pages: Targets
  (/settings/thresholds) owns the per-metric target-range editor and
  Sources (/settings/sources) owns the source-priority and device-type
  ladders. Each is its own left-nav entry and route, served by the
  dynamic [section] route. The former /settings/sources permanent
  redirect is removed since the route now renders the page directly.
- Rename the AI Insights settings section and nav label so the AI nature
  is explicit: 'AI Insights' (EN) / 'KI-Auswertungen' (DE), replacing the
  bare 'Insights' / 'Auswertungen'.
- Each page renders its own h1 heading consistent with sibling settings
  pages.

Drop the now-unused embedded mode from SourcesSection. Update the section
titles and descriptions across all six locale bundles.

+ * `<ThresholdsSection>` — route-level wrapper for `/settings/thresholds`
+ * (the "Targets" / "Zielwerte" page).
  *
- * v1.4.34 IW-D — section was renamed "Zielwerte & Quellen" / "Targets &
- * Sources" and absorbs the former `/settings/sources` content. The two
- * editors stay distinct mutation flows (`/api/user/thresholds` for
- * ranges + `/api/auth/me/source-priority` for source ladders) so a save
- * on one half never disturbs the other; presenting them on a single
- * page collapses two adjacent sidebar slots into one and matches the
- * Settings nav audit (§7.1 item 3 in
- * `.planning/round-v1433-audit-menu.md` — both screens were per-metric
- * configuration shelves and reading them together matches how a user
- * actually thinks about a metric: "for this metric, which sources do
- * I trust AND what range counts as healthy?").
- *
- * `/settings/sources` stays alive as a `permanentRedirect` (see
- * `src/app/settings/sources/page.tsx`) so external bookmarks (iOS
- * Settings deep-links, docs) keep resolving.
+ * v1.8.7.1 — Targets and Sources are two separate settings pages again.
+ * This page owns only the per-metric target-range editor
+ * (`/api/user/thresholds`); the source-priority ladders moved back onto
+ * their own `/settings/sources` page (`<SourcesSection>`). The two were
+ * merged into one "Targets & Sources" page in v1.4.34 IW-D, but the
+ * combined surface ran long and the two editors drive distinct mutation
+ * flows, so each concern is self-contained on its own page.
  *
  * Visual structure on this page:
- *   1. Section header (combined title + description).
- *   2. `<ThresholdsEditorSection>` — per-metric range inputs (top).
- *      The editor card kept its own affordance row (icon, reset-all
- *      button) so the action surface stays compact.
- *   3. `<SourcesSection>` body — per-metric source priority + the
- *      two-axis device-type expander (bottom). The inner section's
- *      header was suppressed in `mode="embedded"` because the page
- *      header above already names the surface.
+ *   1. Section header (title + description).
+ *   2. `<ThresholdsEditorSection>` — per-metric range inputs. The editor
+ *      card keeps its own affordance row (icon, reset-all button).

  * v1.4.16 phase B6: file renamed from the historic
  * `thresholds-settings-section.tsx` (`<ThresholdsSettingsSection>`)
