fix: reject empty pages at construction (v0.1.1)

Browse Source 
empty pages gave max_pages=0; get_page(0)/start() then IndexError'd on self.pages[0].
guard in __init__ with a clear ValueError instead of a deferred crash at render.

verified: ButtonPaginator([]) -> ValueError; non-empty and single-page intact.
