feat(cli): improve quota display in /stats command and footer

- Updates /stats and /stats session to show available quota even without usage.
- Refines QuotaStatsInfo styling to match design: bold percentages and improved spacing.
- Fixes reset time formatting ('Resets in') and visibility in the model usage table.
- Standardizes column widths in StatsDisplay to prevent truncation of quota info.
- Improves formatResetTime resilience to handle various date formats and small offsets.
- Ensures informational quota text renders consistently for auto-models.
