added Orca card countdown to the client's card when searching for a client. If the client is early for the Orca, it will appear on the card like other countdowns already in place.
added Orca card on the Settings page.
added countdown separation. Previously, countdowns for shopping and sleeping bag / backpack were triggered together, causing eligibility issues. Now, countdowns are separated so that only the relevant one is activated based on what the client took.
fixed countdown issue after check-in: bug where the countdown was being updated even if a client checked in but the requested item (like a sleeping bag) was unavailable is fixed. Now, countdowns will only activate if the item is actually available and taken.
added spinner for search to avoid needing multiple clicks on the search button.
added last Orca card info to Profile and Force check-in modal.
