style(FR-1825): fix BAIPropertyFilter tooltip text color to white (#4893)

# Change tooltip color from token.colorError to red in BAIPropertyFilter

This PR changes the tooltip color in the BAIPropertyFilter component from using the dynamic token.colorError to a static "red" color value. This ensures consistent error indication regardless of the current theme token configuration.
