feat(issue-list): redesign table to match Sentry web UI

Redesign the `sentry issue list` table to match the Sentry web UI issue
stream layout with better information density and visual clarity.

Column layout:
  SHORT ID | ISSUE | SEEN | AGE | TREND | EVENTS | USERS | TRIAGE

Key changes:

- Sparkline trend graphs using Unicode block characters (▁▂▃▄▅▆▇█)
  with bucket-averaging downsample, rendered via new sparkline module
- TREND column with sparkline + substatus label (New, Ongoing,
  Regressed, Escalating), auto-hidden on narrow terminals (<100 cols)
- TRIAGE column combining priority and Seer fixability into a composite
  score: impact×0.6 + fixability×0.4, colored by tier
- 2-line default rows (title+subtitle, sparkline+substatus, id+alias)
  with --compact flag for single-line condensed output
- Row separators between data rows for visual clarity
- Request groupStatsPeriod=auto from the API for sparkline data

Text table improvements:

- Row separator support (dimmed horizontal dividers between data rows)
- Multi-line cell width calculation fix: split on newlines and take max
  line width instead of summing across the entire string

Removed columns: LEVEL, ALIAS (merged into SHORT ID), ASSIGNEE, PRIORITY
(replaced by TRIAGE). Renamed COUNT → EVENTS.
