refactor(gateway): replace flat-file import shims with installed package
Install bot_bottle via pip in Dockerfile.gateway instead of COPYing
individual .py files flat under /app/. This eliminates the try/except
import shims in egress_addon_core, dlp_detectors, egress_addon,
supervise, supervise_server, and git_http_backend that existed only
to support the flat-bundle layout.

Adds bot_bottle/constants.py as a single source of truth for
IDENTITY_HEADER and GIT_GATE_TIMEOUT_SECS, removing the duplicated
literal definitions in egress_addon.py, supervise_server.py,
git_http_backend.py, and git_gate_render.py.

Test files updated to match: test_supervise_server.py drops the
sys.path.insert hack in favour of direct package imports; the
egress_addon test shims no longer pre-populate sys.modules with a
bare egress_addon_core alias.

"""Unit: LOG_FULL credential redaction in _log_request / _log_response (issue #257).
egress_addon.py is gateway-only code that depends on mitmproxy, which is
not installed on the host. This file pre-populates sys.modules with the
minimum mocks needed so EgressAddon can be imported and tested without the
