Fix country/language selectors: Radio+flag-emoji values broke single-select (US never applied); use Dropdown with clean MX/US, en/es values

Ask tab: show a thinking indicator while the reasoning model works (was just slow, looked frozen)

US-aware Capture/Ledger + wire in the reasoning LLM agent (Qwen3-8B via vLLM/Modal) with router fallback

Fix: store session-id in gr.State instead of the sqlite Ledger (deepcopy of Connection was breaking every session)

English-default UI + bilingual agent + USA tax support (Schedule C/SE/federal) and expanded US+EN regulation corpus

PocketAccountant: custom ledger UI + deterministic agent (engine, ledger, retrieval, classifier)
