DS-072: Centralize locale-aware number and date presentation

[IbrahimIjai]

Context

Prices, percentages, compact values, timestamps, and dates must be consistent
and ready for users outside the default locale.

Scope

• Add presentation helpers built on Intl.NumberFormat and Intl.DateTimeFormat.
• Cover price, token amount, percentage, compact number, date, time, and relative time.
• Define explicit fallback behavior for invalid input and unavailable data.
• Keep raw financial calculation outside formatting helpers.

Acceptance criteria

• Callers can provide locale and currency without changing calculation precision.
• Negative zero is normalized for display.
• Very small values have a documented less-than display strategy.
• Server and client output remain hydration-safe for the configured locale.
• Tests cover at least two locales, large/small values, negative zero, and invalid input.

Out of scope

• Translating application copy.
• Currency conversion or exchange-rate fetching.
