refactor(pixel): use consent queries in autocapture + fix SnippetOptions type

autocapture.ts — replace 3 consent string comparisons:
- form submit guard: getConsent() === 'none' → !canTrack(getConsent())
- email hash gate: consent === 'full' → includesUserId(consent)
- link click guard: getConsent() === 'none' → !canTrack(getConsent())

snippet.ts — replace inline literal union 'none' | 'anonymous' | 'full'
with the ConsentLevel type from @imtbl/audience-core. This was the one
place consent values were defined outside the single source of truth.
