Typed Prisma queries, bcrypt native, CSP nonces, /api/me/import, more tests

Typed Prisma queries
- where: any in app/api/workouts/route.ts (GET + POST) and
  lib/db/workouts.ts replaced with Prisma.WorkoutWhereInput +
  Prisma.WorkoutCreateInput + Prisma.DateTimeFilter. Catches typos
  at compile time and surfaces query shape directly in tooltips.

Workout import endpoint tests (tests/routes-import.test.ts)
- 7 tests covering /api/workouts/import/save: 401 unauthenticated,
  empty workouts rejected, case-insensitive name matching against
  existing exercises, new-exercise creation with isCustom=true and
  type='other' default, explicit existingExerciseId honored over
  name lookup, multiple workouts per call, sequential setNumber
  per exercise per workout.

bcryptjs -> bcrypt (native)
- Roughly 10x faster than the pure-JS implementation under load —
  login latency drops from ~250ms to ~25ms. Hash format is fully
  cross-compatible with bcryptjs ($2a$ / $2b$ both verify), so
  existing user passwords keep working without migration.
- Dockerfile builder stage adds python3 + make + g++ as a safety net
  for native node-gyp compilation on alpine when prebuilt binaries
  aren't available.
- Runner stage explicitly COPYs node_modules/bcrypt so the .node
  binding is unambiguously present even if Next.js standalone
  tracing somehow misses it.
- StartOS package's changeAdminCredentials.ts keeps bcryptjs (it's
  bundled by ncc into a single JS file and runs only on the rare
  admin action; native bcrypt would require shipping the .node
  binding through ncc which it doesn't handle gracefully).

CSP nonces (middleware.ts + next.config.js)
- Per-request nonce generated in middleware. Forwarded to Next via
  the x-nonce request header, which Next 13.4+ automatically stamps
  onto its inline bootstrap scripts. CSP response header includes
  `'nonce-${nonce}' 'strict-dynamic'`, dropping the previous
  `'unsafe-inline'` from script-src.
- Static CSP removed from next.config.js (middleware-set headers
  override static ones, so keeping both was redundant).
- Middleware matcher widened to all paths except static assets so
  the CSP applies to every page response. Existing /main + /api
  auth gating preserved.
- style-src keeps 'unsafe-inline' — Next/Tailwind still inject
  critical inline <style>; tightening that requires hash-based
  style-src or per-style nonce stamping (Next doesn't auto-do
  either). Worth a follow-up if you want the cleanest possible CSP.

/api/me/import (mirror of /api/me/export)
- Accepts the same JSON shape /api/me/export emits (schema string
  validated: only `proof-of-work-export@1` accepted today).
- mode: 'merge' (default) — adds imported rows; existing exercises
  with matching names are NOT overwritten (the user's custom version
  wins). All workout sets with a known exercise get rebound to the
  user's actual exercise id via name lookup.
- mode: 'replace' — wipes the user's exercises/workouts/sets first,
  then imports. Requires `confirm: "REPLACE"` in the body.
- Always scoped to the actor — never touches other users' data.
- Profile/admin flag/sessions/InstanceSettings deliberately not
  imported (account identity stays put).
- 7 tests cover: 401, schema rejection, merge create+skip, replace
  confirmation gate, replace wipes-then-imports, isolation across
  users.
- ExportMyData component grew Import (merge) + Import (replace)
  buttons with native browser confirm() before the destructive
  replace.

Test suite now 81 tests across 9 files in ~2.6s.
