fix(photon): satisfy Windows footgun + CodeQL checks

CI red on three blocking checks; all addressed:

1. Windows footguns: os.killpg() flagged as POSIX-only despite the
   sys.platform != 'win32' guard. Static scanner doesn't see flow.
   Added the documented '# windows-footgun: ok' suppression.

2. test (3): tests/plugins/platforms/photon/__init__.py shadowed the
   real plugin's __init__.py because test_plugin_platform_interface.py
   looks at PROJECT_ROOT/plugins/platforms/<name>/__init__.py with
   PROJECT_ROOT=tests/ (pre-existing bug in that test, made visible
   by the new test directory layout). Dropping the empty test
   __init__.py restores the prior NOTSET parametrize behavior.

3. CodeQL (7 alerts in new code):
   - cli.py: stop printing the first 8 chars of the bearer token after
     login — even prefixes are partial credentials.
   - cli.py: stop printing the first 8 chars of project_secret after
     setup, same reason.
   - cli.py 'hermes photon webhook register': stop dumping the raw
     register-webhook response (contained signingSecret) and stop
     echoing PHOTON_WEBHOOK_SECRET to stdout. Write it directly to
     ~/.hermes/.env (0o600), preserving existing entries; fall back
     to manual instructions only if the file write fails. Photon
     still only returns the secret once; this just doesn't put it
     in scrollback / shell history.
   - cli.py setup + status: rename project_id/project_secret/token
     locals to has_* booleans before printing, breaking CodeQL's
     taint flow through f-string interpolations. Drop diagnostic
     prints of phone / assignedPhoneNumber that flagged as
     'sensitive data' false positives.
   - sidecar/index.mjs: stop returning the raw error message
     (potentially containing stack trace) in HTTP 500 responses;
     supervisor logs the real error to stderr, client only sees
     a generic 'internal sidecar error'.

Validation:
- scripts/check-windows-footguns.py --all → 0 footguns (518 files)
- tests/plugins/platforms/photon/ → 22/22 pass
- tests/gateway/test_plugin_platform_interface.py → 7/7 pass, collects
  NOTSET (matches pre-PR state)
- tests/gateway/test_platform_registry.py → 50/50 pass
- node --check sidecar/index.mjs clean
