* feat(exchange-rates): add Frankfurter as an exchange-rate provider Frankfurter (frankfurter.dev) is a free, keyless FX rates API backed by ECB daily reference rates, with no published rate limit and no auth flow to maintain (unlike Yahoo Finance's reverse-engineered cookie/ crumb auth or TwelveData's fast-exhausting free tier). Follows the Provider::MoexPublic template: Faraday client with retry middleware, SslConfigurable for self-hosted CA support, a light RateLimitable throttle, and a FRANKFURTER_URL env escape hatch for self-hosters. Registered as exchange-rates-only (no security/stock data) and added to the hosting settings dropdown. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(provider): switch Frankfurter to the v2 API v1 is explicitly marked "frozen" on Frankfurter's own root endpoint; v2 is "current" and covers 201 currencies across 84 central banks vs v1's ~30 ECB-only. Confirmed via the v2 OpenAPI spec and live requests: - Single-date lookups now use GET /rate/{base}/{quote}?date=..., which carries weekends/holidays forward server-side (a Saturday returns a real rate directly), so the provider no longer needs its own lookback-window logic. - Range lookups now use GET /rates?base=..."es=...&from=...&to=..., a flat array of { date, base, quote, rate } records (v2's shape) instead of v1's { "rates": { date => currencies } } hash. - Every calendar day in a range is present (v2 gapfills itself), rather than v1's omit-non-trading-days behavior. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(provider): sanitize currency codes before URL path interpolation from/to were only upcased before being interpolated directly into the URL path in fetch_exchange_rate (GET /rate/{from}/{to}). Low risk since currency codes come from validated internal sources, but adds cheap defense-in-depth: strip anything that isn't A-Z, matching the ISO 4217 format real currency codes always take.
