fix: prevent TypeError when calling toFixed on string values from PostgreSQL

PostgreSQL numeric/decimal columns serialize as strings in JSON responses,
causing .toFixed() to throw TypeError when called on string values.

Changes:
- Wrap all .toFixed() calls with Number() for type coercion
- Add division by zero guards for percentage calculations
- Add Number.isFinite() checks for critical display values
- Standardize percentage decimal places to 1 digit for consistency

Affected components:
- my-usage: quota-cards, usage-logs-table
- dashboard: logs, sessions, availability, leaderboard, rate-limits
- quotas: keys, users, providers dialogs and list items
- internal: big-screen dashboard
- shared: session-card, session-list-item, overview-panel, user-quota-header
