* fix(tinkoff): resolve the tradeable listing and price bonds via BondBy
Validated against the live T-Invest API and fixed three correctness issues in
Provider::TinkoffInvest:
- FindInstrument returns several listings per ticker (e.g. SBER on TQBR plus
dark/non-API boards 37M/SPEQ); only the apiTradeAvailableFlag listing has live
prices. resolve_short now ranks tradeable-first (then requested-MIC, then exact
ticker/ISIN) instead of taking the first match, so GetLastPrices/GetCandles
return data. Search now surfaces only tradeable instruments.
- find_instruments no longer hard-filters on apiTradeAvailableFlag, so a
qualified-investor instrument Tinkoff lists but can't API-trade still resolves
(for logos) and otherwise falls back to another price provider.
- Bond nominal comes from BondBy (the generic GetInstrumentBy omits it),
returning the current amortized nominal so percent-of-par converts correctly.
Verified end-to-end: SBER 313.65, T 282.76, LQDT 2.019, and the SFO Split bond
(amortized nominal 417.71) all price; logos resolve to real CDN PNGs.
* fix(tinkoff): honor requested MIC first, guard amortizing bonds, strip suffix
Address review feedback on the resolution/pricing path:
- resolve_short now ranks a requested-MIC match BEFORE tradeability, so a
security is never priced off another exchange's listing (e.g. a MISX security
no longer picks up a tradeable XSPX board's price); tradeability and exact
ticker/ISIN remain secondary tie-breaks.
- Amortizing bonds: BondBy returns only the current nominal, so applying it to
historical percent-of-par closes would underprice them. For amortizing bonds
we now return only the live price and skip the candle history; fixed-par bonds
and equities keep full history. bond_info exposes nominal + amortizationFlag.
- Strip exchange suffixes (.ME/.MOEX/.MISX/.MCX) before querying T-Invest, which
only knows the bare SECID — so a stored "T.MOEX" ticker resolves to "T".
* fix(tinkoff): don't cache nil resolution results (skip_nil) so a transient empty response isn't locked in for the 24h TTL
