MT call, Call connected, Call disconnected, Browser termination, (I-)WLAN
access status and CSG cell selection no longer fall back to the generic
"send a bare notification" prompt:
- MT call (TS 31.111 7.5.1A.2): transaction identifier, calling party number
+ TON -> Address (EFADN BCD coding, encBcdDigits/eventAddressTlv),
subaddress, IMS URI, media type; source network.
- Call connected (7.5.2A.2) / Call disconnected (7.5.3A.2): transaction
identifier, near/far-end source select, media type, and a cause - absent,
the zero-length radio-link-timeout form or custom bytes (the hex field shows
only for "custom").
- Browser termination (TS 102 223 7.5.9.2): user / error cause.
- (I-)WLAN access status (TS 31.111 7.5.1.2): no coverage / coverage /
connection on-going.
- CSG cell selection (TS 31.111 7.5.3.2): status + selection mechanism,
optional access technology, CSG ID, HNB name and PLMN ID; source network.
The device-identities source (TS 102 223 8.7: 82 terminal / 83 network) is now
selectable: EVENT_FORMS carries a fixed `src` or a `srcField`, and
_send_event_download()/`/api/event-send` take an `event_src` override (an
invalid value falls back to the terminal).
Tests: the BCD/Address builders, each event's build vectors, the "no not_yet
left" guard and the server source override. Help EN/RU, both AGENTS files;
sw cache simple-v348.
