chore: bootstrap Nx workspace per ADR-0002

Initialize the Nx 22 monorepo via copy-from-scratch (the
create-nx-workspace 'apps' preset is now mapped to nrwl/empty-template
in Nx 22). Workspace files extracted from a scratch generation and
adapted to the project:

- package.json: name 'apf-portal' (renamed from @org/source default)
- tsconfig.base.json: customConditions aligned to apf-portal; strict TS
  extended per ADR-0004 with noUncheckedIndexedAccess,
  exactOptionalPropertyTypes, noPropertyAccessFromIndexSignature
- nx.json: nxCloudId stripped (on-prem, no Nx Cloud SaaS)
- .prettierrc: project convention (singleQuote, semi, printWidth 100)
- pnpm-workspace.yaml: apps/* and libs/** for the integrated layout
- pnpm-lock.yaml committed

Plugins for Angular, NestJS, Vite, ESLint will be added in the next
phase when apps are generated. The auto-generated CLAUDE.md / AGENTS.md
/ .claude/ / .github/ from the bootstrap were intentionally not
carried over (we keep our own CLAUDE.md and use Gitea, not GitHub).
