Replace the Phase-0 placeholder password encryption with real RSA
(PKCS#1 v1.5). encrypt_password now builds an RSA public key from the
getSecureKey modulus/exponent (RSAPublicNumbers, e=int(hex,16),
n=int(hex,16)), encrypts the UTF-8 password, and returns hex (documented
assumption -- base64 is the one-line fallback noted in the docstring).
get_secure_key now returns the inner data dict to match the new contract;
pc_login keeps {account, password} with a comment on the username/password
and account/pwd fallbacks if pcLogin rejects.
Extend normalize_wechat_type with the Phase-0 confirmed codes:
2 -> image, 3 -> image_legacy, 4 -> video, 10 -> system (1 -> text and
-2 -> divider unchanged; 6/9/13/15/21/22 stay unknown until confirmed).
Tests:
- encrypt_password round-trip: generate an RSA keypair, build secure_key
from its public numbers, encrypt, then decrypt with the private key and
assert the original password comes back. Pins 512-hex output for a
2048-bit key. No network.
- Parser parametrize table extended for the new codes (and a downstream
message-fixture assertion updated from unknown -> image_legacy).
Suite: 87 -> 97 passing. ruff check clean.
