v3.23.7: the proactive log survives a TERMINAL PROFILE re-send

Pressing the Phone tab's Send (or Rescue) re-sends the profile and starts a
new CAT session.  The log was cleared with the rest of the session state,
losing the only record of the card's proactive commands - a common
tweak-the-profile-and-resend loop wiped the history every time.

_resend_terminal_profile now calls _mark_proactive_session(
'terminal-profile') instead: the entries stay, _PROACTIVE_SESSION_START
restarts (so the new session's elapsed values begin at 0) and a boundary
marker entry is appended.  The PWA renders the marker as a
'- TERMINAL PROFILE re-sent - new CAT session -' divider (EN/RU).

Equip / disconnect keep the full clear (a card change); the pending-command
cancel, menu timeout and event list reset are unchanged.

Tests: the marker keeps the entries and restarts the timer, the reset still
clears, the re-send path pinned by source (Python) and the renderer's marker
branch (Node).  857 frontend + 842 Python; sw cache simple-v420.
