// ---- Forgot-password flow (fixes #15282) -----------------------------
//
// Mirrors api/apps/restful_apis/user_api.py /auth/password/... endpoints.
//
// Contract divergence from Python: the Python endpoint returns a
// rendered image (Content-Type: image/JPEG) from the python-captcha
// library and stores the captcha under captcha:<email>. This Go port
// returns a server-issued captcha_id plus a PNG captcha image (as a
// data URL the FE drops straight into <img src>), and stores
// captcha:<captcha_id>. The plaintext text only ever appears as
// raster pixels — the OTP step reuses the captcha_id to look the
// expected text up server-side.
//
// The PNG is rendered using stdlib `image/png` + a hand-rolled 5x7
// bitmap font in internal/utility/captcha_png.go, because no Go
// captcha library is vendored in go.mod (no network during build).
// PR #15290 review (Hz-186) explicitly asked for a raster after the
// earlier SVG implementation: the SVG embedded the answer in <text>
// nodes, so a scripted client could base64-decode the response and
// grep the captcha directly. PNG closes that attack — the response
// bytes never reference the original text.
