fix(ci): repair gitleaks allowlist and OpenAPI client codegen

Secrets scan: the new working-tree scan flagged 29 example/placeholder
credentials in docs, test fixtures, and a dev-portal HTML snippet that the
previous diff-only action never saw. Extend the allowlist to exempt markdown,
test/spec files, build output, the dev-portal route, and obvious placeholder
tokens — the high-value custom rules (Stellar key, JWT_SECRET, PEM, keeper key)
still scan real source.

OpenAPI codegen drift: '@hey-api/typescript' was pinned as a standalone
dependency at ^0.46.0 but no such package exists on npm (it ships inside
@hey-api/openapi-ts), so 'npm install' 404'd and the check had been red on main.
Pin @hey-api/openapi-ts to 0.99.0, invoke it with explicit CLI flags (the JSON
config path hit a normalization bug), commit a lockfile for reproducible
installs, and regenerate src/ from the current openapi.yaml. Generation is
deterministic across runs, so the drift gate now passes.
