fix(iris): remove misleading 'All' log option and increase default max lines (#3683)

Drop the 'All' option from the LogViewer dropdown since it was capped at
DEFAULT_MAX_TOTAL_LINES anyway. Increase DEFAULT_MAX_TOTAL_LINES from
10k to 100k so CLI users can fetch more logs when needed.

Fixes #3672
