scp81: UI framing options, permissive TLS, drop the Apache-header mimicry (v2.2.14)

Listener Options block (applied at Start, persisted in localStorage, Reset to
defaults): HTTP framing - chunked body, chunk size (0 = one TLS record),
keep-alive, Connection header, compact headers, Next-URI (unchecked = omit);
script framing - indefinite/definite Command Scripting template, CR tag,
targeted app; link events (now parsed on the common start path, so every mode
honors them). scp81OptionsFromForm() is unit-tested.

TLS is automatic: 'auto' (min 1.0, max 1.2 + :@SECLEVEL=0) is the new
default, all six PSK suites are offered and OpenSSL negotiates the highest;
the negotiated version/cipher is logged (tls-handshake) and reported as
version_seen/cipher_seen in /api/scp81/status, and a handshake failing for a
TLS/cipher reason logs tls-handshake-failed (post-handshake record errors
stay tls-error). tls_version/cipher/keylog/answer_delay stay as API-only pins.

Dropped the Apache-style header mimicry completely: no Date/Server/
X-Powered-By, no Content-Length-before-Content-Type ordering, no Content-Type
on 204 - the minimal response set is X-Admin-Protocol (+ X-Admin-Next-URI /
Targeted-Application), Content-Type on 200s, and Transfer-Encoding or
Content-Length per the chunked flag. Docs, help (EN/RU), READMEs and the
AGENTS notes updated; SW cache otaman-v180.

+The **Options** block (applied at **Start**, remembered in the browser) exposes the HTTP framing (chunked body / chunk size, 0 = one TLS record / keep-alive / Connection header / compact headers / Next-URI), the script framing (indefinite `AE 80 …` or definite `AA` Command Scripting template, comprehension-required tags, targeted application) and link events (all modes, TS 102 223 §7.5.11). TLS has no settings: the listener offers TLS 1.0–1.2 and all PSK suites and lets the card negotiate; the log and state line report the version/cipher actually used, and a TLS/cipher handshake failure is logged as `tls-handshake-failed`.

 **Script** selects the command list served over the session: **None** (leave the server's configured script) or one of the scripts created in the **Scripts** pill; **Restart script** re-queues the selected script with `force`, starting over from the first APDU.
 
 The state line shows the listener, the negotiated identity and live channels (bytes in/out); **Script results (R-APDUs)** lists each served C-APDU with its R-APDU and SW (`done/total` progress); the **HTTP OTA log** records OPEN/CLOSE CHANNEL, SEND/RECEIVE DATA and every TLS/HTTP/script step (`tls-handshake`, `tls-request`, `script-send`, `script-rapdu`, `script-page`, `script-done`, `data-available`, `peer-close`).
