Changes Made

• Make our TUI pagination and CLI list subcommand no longer use total_count and remaining_count from our API since it will be deprecated
• Make our TUI pagination keep track of # of items seen so far (when scrolling to previous page, it shouldn't decrease). However, this isn't necessarily equal to total number of items that exist
• Add --limit option to list subcommands of blueprints and snapshots
  • Breaking: these subcommands only list 20 by default (just like the other ones) instead of all

Testing

• I have tested locally
• I have added/updated tests
• All existing tests pass

whats the effect of taking this || branch only - doesn't this affect how the UI shows the number of total results?
