v0.12.0 — REST API + personal access tokens

A bidirectional API so other apps (Home Assistant, phone shortcuts, scripts,
and the coming MCP server) can read and update the homestead.

- ApiToken model (sha256-hashed, scoped, with prefix/lastUsed/expiry/revoke)
- authenticateRequest() accepts EITHER a NextAuth cookie session OR a Bearer
  PAT; cookie sessions get full access, tokens are limited to their scopes
  (write implies read; resource and global wildcards). ApiError + handleApiError
- Shared service layer (plants/tasks/locations/plant-types) reused by every
  endpoint and, later, the MCP server — logic lives once
- /api/v1: plants (read + add log), plant-types, locations, tasks (read/create/
  complete), and a whoami/discovery root
- Settings → API tokens: create with per-resource read/write checkboxes, raw
  token shown once, revoke; tokens added to backup/restore
- Pure tests for scope matching + token hashing; verified end-to-end (401/403/
  201, lastUsedAt) against a running server
