Calendar Price Field: Increment/Decrement Arrows

Currently, when using the up/down arrows in the calendar's price field, the value resets to zero. The requested behavior is for these arrows to increase or decrease the current price by one increment, allowing for quicker adjustments without manual typing.

The user noted that they spend the majority of their time changing prices and currently have to manually type every amount, as the arrows serve no function since properties do not rent for amounts close to zero.
