New Features: Improvements to UI and performance with large logs

Previously, kubetail loaded the entire log history for each of the source pods on startup but this delayed the startup time and also some caused performance problems in the UI with large logs. This release changes the default behavior of the console and tails logs by default. This release also adds a dropdown feature that allows users to filter logs by a duration (e.g. "10 minutes ago") or by an absolute time range ("Feb 6, 2024 12:00:00 - Feb 8, 2024 15:30:00").
