[Due for payment 2026-06-08] Reduce receipt photo resolution and enable iOS takeSnapshot for faster capture

[cristipaval]

Problem

Receipt capture currently shoots at 12 MP and uses takePhoto on iOS even in the common no-flash portrait case. The high resolution increases capture time, thumbnail generation cost, memory pressure, and upload size — all for an image that only needs to be legible for SmartScan.

Solution

• Drop capture resolution from 12 MP to 6 MP — still plenty for receipt OCR while making capture, thumbnail generation, memory, and upload all cheaper
• Use takeSnapshot on iOS for the no-flash portrait case (Android already does this), falling back to takePhoto when flash is on or in landscape
• Enable video on the iOS camera platform-conditionally to support takeSnapshot
• Merge the now-identical iOS and Android capture files into a shared index.ts
