Hongming Wang 47d3ef5b9e refactor(middleware): extract dev-mode fail-open predicate
AdminAuth and WorkspaceAuth both carried the same 5-line
`ADMIN_TOKEN == "" && MOLECULE_ENV in {development, dev}` check. If a
third middleware ever needs the hatch — or if "dev mode" semantics
change (new env name, allowlist, runtime flag) — the previous shape
made N places to keep in sync and N places a security reviewer has to
audit.

This commit factors the predicate into a single `isDevModeFailOpen()`
helper in `internal/middleware/devmode.go`. Each call site becomes

    if isDevModeFailOpen() { c.Next(); return }

`devmode.go` carries the full rationale (why the hatch exists, why
it's safe for SaaS) so call sites don't need to restate it.

### Also

- Moved the dev-mode env-value set to a package-level `devModeEnvValues`
  map so adding aliases is one line. Matches the existing convention
  (`handlers/admin_test_token.go`) of treating `MOLECULE_ENV != "production"`
  as dev — but stays explicit about which values opt IN rather than
  blanket-accepting everything non-prod.
- Added case-insensitive compare + trim on the env value so operators
  don't have to remember exact casing.
- New `devmode_test.go` unit-tests the predicate directly: 6 cases
  covering happy path, both opt-out signals (ADMIN_TOKEN, production
  mode), short alias, case-insensitive + whitespace tolerance, and an
  explicit negative-space sweep of arbitrary non-dev values
  ("staging", "preview", "test", "devel", "") to lock in that typos
  don't silently enable the hatch.

Existing AdminAuth/WorkspaceAuth integration tests still exercise the
helper indirectly via HTTP — they pass unchanged, confirming the
behaviour is preserved.

### No behavioural change

Before and after this commit, `go test -race ./internal/middleware/`
reports identical results. Zero production surface change — this is a
pure refactor, but it collapses the dev-mode seam from two inline
blocks into one named predicate, which is the shape future
contributors (and security reviewers) can follow.
