Homebuying Budget Container — Build Spec

This replaces the internals of the existing Homebuying Budget container in the buyer profile. Layout, colors, and placement within the larger page are unchanged — this is a self-contained update to the card only.

What's new:

• Buyers can now set a lower Funds Available amount, mirroring the existing Max Monthly Payment reduction that already ships today.
• Both amounts use a typed number field with ± steppers and quick preset chips — no slider.
• Both fields are hard-clamped so a buyer can only enter a value at or below the approved amount from their loan approval — never above it.
• When a value is lowered and saved, the card gets a light blue tint and an “Adjusted” badge, and the toggle link relabels to “Edit amount” so an active override is visible without opening the panel.
• The Age Restricted Communities section below is unchanged.
