Artem Danilov 9de9a23ce2 feat(prices): add T-Invest (T-Bank) securities + brand-logo provider (#2408) ...

Adds Provider::TinkoffInvest, a token-based securities provider built on the
public T-Invest REST gateway (invest-public-api.tinkoff.ru/rest). It serves
prices for Russian instruments (shares, ETF/БПИФ, bonds) and, crucially, brand
logos via the T-Invest CDN — the authoritative logo source for MOEX
instruments, which ISS (MoexPublic) does not provide.

- Registry: register `tinkoff_invest` under the :securities concept; token via
  ENV TINKOFF_INVEST_API_KEY or encrypted Setting.tinkoff_invest_api_key.
- Logos independent of the price provider: Security#import_brand_logo consults
  T-Invest for a logo whenever a token is configured (after the price-provider
  metadata fetch, so it never short-circuits website_url backfill). Gated on
  token presence, not the securities checklist.
- display_logo_url: with no website domain, a stored provider logo (T-Invest)
  now beats the ticker-only Brandfetch lettermark; when a domain exists,
  Brandfetch still wins (unchanged).
- MoexPublic no longer reports moex.com as the issuer website — it's the
  exchange, not the issuer, and would make Brandfetch render the exchange logo
  for every instrument and shadow the real brand logo.
- Prices: GetCandles (daily, paged) + GetLastPrices; Quotation units+nano/1e9;
  bonds priced as percent-of-par x nominal (missing nominal raises, not 0).
- Settings: encrypted token field (always shown) + provider checkbox + en locale.
- Tests for search/info/logo-url/prices/bond/incomplete-candle and display logic.
