fix(popup): use hostname-aware domain matching to prevent false positives

The noise filter used naive String.includes() on the full URL, causing
blacklist entry 'x.com' to match netflix.com (since 'netflix.com'
contains 'x.com' as substring). This made Netflix tabs disappear when
the filter was enabled.

Fixed by extracting the URL hostname and matching at domain boundaries:
- Domain entries (x.com): hostname === domain || endsWith('.' + domain)
- Prefix entries (amazon.): startsWith || includes('.' + domain)
- Keyword entries (jira): substring fallback on full URL
