fix: correct HTMX polling and Alpine state integration

Fix status and results not loading by removing HTMX conditions that
don't react to Alpine state changes and simplifying visibility logic.

Problems:
1. HTMX trigger conditions [analyzing] don't react to Alpine state
2. Status div hidden initially (x-show with hasStatus requirement)
3. Chicken-and-egg: hasStatus needed to show, but only set on response
4. HTMX doesn't poll hidden elements effectively

Solution:
- Remove HTMX conditional triggers [analyzing], [analyzing && !hasResults]
- Simplify status visibility: x-show="analyzing && !hasResults"
- Let HTMX poll unconditionally with "every 1s"
- Alpine x-show controls visibility, HTMX polls when visible
- Cleaner event handlers with explicit response checking

Changes:
- Status: removed hasStatus from x-show condition
- Status: hx-trigger="every 1s" (no conditions)
- Results: hx-trigger="every 1s" (no conditions)
- Better response validation in @htmx:after-request

Result:
- Status updates appear immediately when analyzing starts
- Status polls continuously until results arrive
- Results polling works correctly
- Proper state transitions: analyzing → hasResults
