Bug fix and UI improvement

Hand History - New "Hands" tab for saving and reviewing your poker hands. Each saved hand captures hero hole cards, board cards across all four streets, opponents, the action sequence, and a net result. - Hand history rows display hero cards and community cards as styled chips (red/black suit colors) instead of plain titles, so hands are recognizable at a glance. - All Hand History UI strings localized. Live Activity (iOS Lock Screen + Dynamic Island) - Starting a live cash session now presents a Live Activity on the Lock Screen and Dynamic Island showing the running session timer, total buy-in, and each individual buy-in as a chip. - Updates when buy-ins are added; ends automatically on session completion. - Tapping the Live Activity opens the app directly to the Active Session screen via a pokerledger:// deep link. Session entry defaults - New live cash sessions pre-fill the initial buy-in to 100 × the big blind of the selected stakes. Updates if you change stakes. - Ending a session pre-fills the final chip count to the session's total buy-in. Analytics - Integrated Firebase Analytics (FirebaseCore + FirebaseAnalytics) for daily-active-users and feature-usage logging. No personally identifying information is collected. Internal - Statistics tab reordered. - Cached currency formatters in the Live Activity widget to keep widget renders within iOS's CPU budget.

NEW — Equity Calculator • Dedicated Equity tab: compute how often your hand or range beats your opponent's on any board (flop, turn, river, or preflop). • One-tap range filters for Full House, Flush, Straight, Set, Two Pair, Overpair, Top Pair, Pair + Flush Draw, Pair + Straight Draw, Flush Draw, Open-Ended Straight Draw, Gutshot, and Backdoor Flush Draw — each combo lands in exactly one bucket so counts never double. • Fine-tune the range by tapping individual combos. • Or switch to Hand mode and pick two specific cards for either player. • Monte Carlo engine runs 25,000 trials per calculation, accurate to ±0.3%. NEW — Multi-Currency Support • Track sessions in USD, CAD, or CNY out of the box. • Add any ISO 4217 currency (JPY, EUR, GBP, and more) from Settings. • Statistics aggregate across mixed-currency sessions using live exchange rates. • New sessions default to USD so your existing data is unaffected. IMPROVEMENTS • Done button above the keyboard on every numeric input. • Faster range editing — heavy computation now runs in the background so picking board cards stays responsive. • Smoother live-session clock — the rest of the screen no longer redraws every second. • "Rates last updated" now reflects your most recent refresh. • Full translations of the new features in English, Spanish, Simplified Chinese, Vietnamese, and Tagalog.
