curses.use_default_colors() raises on terminals (e.g. serial consoles
using TERM=linux/vt100) whose terminfo lacks default-color support;
init_colors() now falls back to an explicit black background and caps
the "disabled" color to 8-color terminals.
--reissue without --email silently sent no mail when the CN wasn't in
openvpncertupdate-metadata.json, even though its email was already
embedded in the cert's index.txt subject (via EASYRSA_REQ_EMAIL) and
the TUI already fell back to it. Since build_client_full() always
writes that subject field whenever an email is known, metadata.json
was a redundant, driftable copy — remove it and have get_email() read
index.txt directly, picking the last non-revoked entry for a CN since
index.txt can contain revoked/duplicate lines for the same CN.

Cryptgeon's real protocol (verified against upstream occulto/frontend/backend
source) never matched what create_note() sent: it used a SHA-256-derived key
instead of the raw one, a single-blob ciphertext instead of the delimited
AES-GCM--nonce--ciphertext format, an empty meta field instead of a JSON
string, and a hash-bang URL instead of the real /note/<id>#<key> route -
notes uploaded fine but were undecryptable in the browser.
Also adds CA_PASSPHRASE auto-detection/prompting ("" auto-detects an
encrypted CA key and prompts, "!empty"/"!ask" opt out of/force the prompt)
and an external .conf file (--config / CONFIG_PATH / <script>.conf) that can
override the SETTINGS block without editing the script.
