Paka 0.15.0 capture preview 3

Third preview of 0.15.0, focused on the photo review/crop flow and UI polish, on top of capture previews 1–2.

• Chosen/imported photos now go through the same review and crop screen as captured ones before saving, including two-photo front/back batches
• Crop corners use larger invisible touch targets so resizing feels snappier on the Light Phone III
• While cropping, tapping the photo rotates the working image 90° counter-clockwise with an immediate hard-cut preview; rapid repeated taps no longer crash the crop screen
• Details, manual entry, settings, and submenus share the app typography more consistently, with an optional official-font toggle in hidden Developer settings
• Bottom controls (gear, plus, barcode, code/asterisk) were sharpened and rebalanced to the same visual envelope without changing sizes; the original Paka gear is the default settings icon again, with the Light SDK gear as an optional Developer setting
• The transitive ACCESS_NETWORK_STATE permission from CameraX/Media3 is explicitly removed from the merged manifest — the APK requests camera only

Before stable 0.15.0, this still needs a hardware battery/lifecycle pass covering camera, torch, brightness, TOTP ticking, and PDF/photo rerender cleanup.

Signed like the regular releases, so it installs as an update over an existing Paka installation (including earlier previews). Source is on the preview/document-capture branch; main remains at 0.14.0.
