feat: institutional + support + training admin sections (backend + frontend)

Ship three fully-wired admin areas end-to-end with APIs, seeds, tests and docs.

Backend (new `encoach_lms_api` addon + existing addons):
- Institutional: academic years/terms, departments, admission registers & admissions,
  courses/batches, lessons, fees (terms + student fees + invoicing with income-account
  auto-wiring), gradebook (assignments/grades), library, facilities (encoach.asset),
  student leave, result templates + marksheets (incl. delete-with-cascade).
- Support: `encoach.ticket` model + CRUD/assignee routes; payment records derived
  from `op.student.fees.details` and `account.move`; platform settings backed by
  `encoach.code` and `ir.config_parameter` (packages + grading config).
- Training: `encoach.vocab.item` + `encoach.grammar.rule` (plus progress models)
  with CRUD, pagination, search/level filters, and upsert-style progress endpoints.
  Odoo 19 compatibility: `_sql_constraints` replaced with `@api.constrains`;
  `ValidationError`/`UserError` mapped to HTTP 400.

Frontend:
- Rewire institutional admin pages (Academic Year Manager, Admissions, Courses,
  Lessons, Fees, Gradebook, Library, Facilities, Student Leave, Marksheets,
  Taxonomy, Resources) to real APIs with React Query invalidation and dialogs.
- New typed services: `payments.service.ts`, `platformSettings.service.ts`,
  `training.service.ts`. Updated `fees/gradebook/lms/courseware/taxonomy/
  resources/student-progress/generation` services + related types.
- Rewrite `VocabularyPage`, `GrammarPage`, `PaymentRecordPage`, `SettingsPage`,
  `TicketsPage` to consume live data with search/filter/progress/CRUD flows.
- New shared components: `TaxonomyCascade`, `MaterialViewer`, `teacher/TeacherLibrary`.
- Favicons/branding assets and misc. UX polish across teacher/student pages.

Tooling & QA:
- Seeders: `seed_demo.py`, `seed_demo_data.py`, `seed_institutional.py` (idempotent,
  covers institutional + support + training fixtures incl. income-account wiring).
- API write-flow test suites: `test_write_flows.py` (institutional),
  `test_support_flows.py` (support), `test_training_flows.py` (training),
  `test_ai_full.py`. All suites pass end-to-end.
- Docs: add `docs/PROJECT_SUMMARY.md` with per-section scope, artifacts and QA.
- `.gitignore`: ignore `pgdata_bak_*/`, `frontend/.vite/`, `frontend/dist/`,
  `frontend/node_modules/`.
