The counter an operation consumed was re-entered by the PWA on every send
(the form field was filled from the preset and posted back), so a stale tab
could send a value the card rejects (cntr_low), and typing in the field
silently wrote the preset. Now the store is the single source of truth and
the form field is a per-send override (Option B).
- _preset_counter_seed: an explicit `cntr` in the request wins (a hand send,
the counter probe or a pre-built packet may deliberately pick one);
otherwise the preset store's value for the packet's keyset. Wired into
/api/send-ota (the APDU path; the pre-built `sp` path keeps the caller's
bookkeeping value - the packet carries its own counter), /api/ram-install,
/api/ram-install-app, /api/cap-compat, /api/tar-probe and /api/sp-verify
(the reference must use the counter the JS packet was built with).
- the send-ota response echoes the effective `cntr` (a caller that omitted
one learns what was used) and the OTA SEND log line prints it.
- persistence is unchanged and monotonic (presets.set_counter refuses
backwards writes), pinned by tests: an explicit lower counter is used for
the packet but never lowers the store, a higher accepted one is saved.
- PWA: the Secured packet counter field starts empty with the preset's next
value as its placeholder (auto: <cntr>); typing affects that send only and
is never written to the preset (spCntrSyncPreset is gone), spParams /
getRamSpParams omit an empty counter, the RAM/send flows sync only the
local preset copy (forward-only) instead of filling the field, the +/-
buttons start from the effective value, and the preview/verify packet is
built from the effective counter (genSp). Placeholder translated EN/RU.
- the runner and /api/counter-probe keep their existing seeding (the probe
already starts at the failed value and walks above it).
