fix: use format_tokens() in render_live_sessions (#133)

[microsasa]

Fixes #133

Changes

src/copilot_usage/report.py — render_live_sessions now calls format_tokens() instead of raw :, f-string formatting for output tokens, matching every other token-displaying call site.

tests/copilot_usage/test_report.py:

• Updated test_active_session_shows_output_tokens assertion from "15,000" → "15.0K"
• Added test_active_session_shows_output_tokens_m_suffix verifying values ≥1,000,000 render with M suffix (e.g. 1.5M)

Verification

All 405 tests pass. Coverage at 97.97% (≥80% required). Ruff, pyright, and bandit all clean.

Pull request overview

This PR fixes an inconsistency in the copilot-usage live report by ensuring output-token counts are formatted with the shared format_tokens() helper, matching the formatting used elsewhere in the reporting module.

Changes:

• Updated render_live_sessions() to use format_tokens(_estimated_output_tokens(...)) instead of comma-separated integer formatting.
• Adjusted the existing live-session test assertion to expect K-suffix formatting.
• Added a new test to verify M-suffix formatting for values ≥ 1,000,000 in the live view.
