Fix can_process_url() to receive normalized URL in deep crawl strategies

Pass the normalized absolute URL instead of the raw href to
can_process_url() in BFS, BFF, and DFS deep crawl strategies.
This ensures URL validation and filter chain evaluation operate
on consistent, fully-qualified URLs.

Fixes #1743
