Run on Bun: bun install, bun --bun next, both dev2 sites on Bun (#222)

* Run on Bun: bun install, bun --bun next, both dev2 sites on Bun

Moves logicsrc.com and app.logicsrc.com (one image) off Node + npm onto Bun,
following the fleet recipe (phonenumbers.bot pilot).

- Package manager: bun.lock migrated from package-lock.json, so every resolved
  version is unchanged; packageManager bun@1.4.2. Root scripts run each
  workspace with `bun run --cwd <dir>` instead of `npm --workspace`.
- Bun 1.4.2, not the fleet's 1.4.0: 1.4.0 re-resolves this workspace's `file:`
  cross-references differently on every install, so its own lockfile never
  passes --frozen-lockfile. 1.4.2 is stable on it.
- Runtime: logicsrc-web runs `bun --bun next build/start`; apps/pwa (Express,
  app.logicsrc.com) runs `bun src/server.mjs`.
- Image: .nixpacks/Dockerfile (the path both dev2 compose stacks build) is now
  a hand-written oven/bun image carrying the whole workspace, run as the
  non-root bun user. ENTRYPOINT stays `bash -l -c` so a compose `command:` is
  one string, as before; app.logicsrc.com's compose starts it with
  "npm --workspace @logicsrc/pwa run start", which .nixpacks/npm (the image's
  only `npm`) turns into `bun run start` in apps/pwa. Port 3000, the PUBLIC_URL
  build arg and the / health path are unchanged. The nixpacks .nix and
  build.sh are gone.
- CI: both workflows install with bun and run every script through bun (Node
  stays only as the interpreter for vitest/tsc/node --test/Playwright, as
  before), and CI now boots the site under Bun.

* ci: boot check on port 3100 and stop it before Playwright needs 3000

* fix(web): keep next dev on port 5174, which Playwright waits on
