Pasquale/cui 117 build a select like button

[pasqualevitiello]

TLDR: This PR introduces a SelectButton component, helpful when you need a button that looks like a select trigger (eg. in combobox, autocomplete, menu and popover triggers).

Summary by cubic

Adds SelectButton to give Combobox, Menu, and Popover a select-like trigger, with docs and examples. Implements CUI-117.

• New Features

  • SelectButton: standalone, styled like SelectTrigger; usable as a render prop on other triggers.
  • New example p-combobox-18 and docs showing ComboboxTrigger with SelectButton.
  • Updated timezone combobox demo to use SelectButton.

• Refactors

  • Triggers (Combobox, Autocomplete, Menu, Popover) now render children to support custom trigger content.
  • Added Icon elements with data-slot for Combobox/Autocomplete triggers.
  • Removed unused bookings-saved-filters example.
  • Upgraded @base-ui/react to 1.1.0.
