fix(formatters): address second round of Seer/BugBot review feedback

- escapeMarkdownCell: replace newlines with space to prevent multi-line
  values from splitting a markdown table row across multiple lines
  (affects log messages, breadcrumb messages, tag values, any user content)
- formatLogTable / formatTraceTable: wire into the non-follow batch list
  paths (log/list.ts executeSingleFetch, trace/list.ts) — replaces the
  formatLogsHeader + formatLogRow loop so batch mode gets proper
  Unicode-bordered table rendering, streaming/follow mode still uses rows
- project/view.ts: restore muted() styling on the multi-project divider
  by importing and calling divider(60) instead of bare "─".repeat(60)
