<brief>Audit detail routes lacking back affordances; add a shared header/back pattern.</brief>
## Background / current behavior
Individual plant pages (and other detail routes) have no in-page "back" except global nav. Affects many detail pages under `src/app/`.
## Expected behavior
Every detail page has a consistent back control to its parent list/index. Prefer a shared header/back component.
## Acceptance criteria
- [ ] Audit all routes in `src/app/` and list detail pages missing back in the PR description.
- [ ] Shared back affordance applied consistently.
- [ ] Playwright: `tests/e2e/navigation.spec.ts` or per-module — open plant/note/list (and other) detail routes → Back visible and returns to parent.
## Priority
P1 (batch step 5). Task brief: `docs/tasks/84-back-navigation.md`.
