fix(actions): JSON kinds match --kind, and harden parsing and ranges

- JSON named kinds by their Rust names (public_expose, tender_offer,
  stock_dividend, reverse_split) while --kind and MCP take expose, tender,
  stock-dividend, reverse-split, so an output kind could not be passed
  back. JSON now uses the input names; old cache entries still read, and
  --kind also accepts underscores.
- {"dividend": null, "today": "..."} failed to parse and aborted the
  whole command; a null list beside scalars now reads as none.
- An extreme --from panicked on the default 30 days; it is an error now.
  The 366-day limit let 367 days through; it counts both ends now.
- An entitlement without a cum date sat on its ex date under a note that
  calls DATE the cum date. The table marks it (ex) and says what that
  means; JSON leaves cum_date out, as before, and the docs say so.
- A dividend's currency was ignored; one not in IDR now carries currency
  and the table shows it instead of Rp.
- The live check no longer fails a quiet month's empty calendar.

its ex date, marked `(ex)` in the table, and JSON leaves `cum_date` out.

carries `currency` (e.g. `USD`). JSON's `kind` is the name `--kind` takes.
Both need your Stockbit session and answer `AUTHERROR` without one. Stockbit
serves one kind per request, 1 s apart, so a first call with every kind takes
