Add an ARMv7 Alpine package base for the iPad mini 1 RAM recovery. The builder exports a hash-bound archive using pinned Alpine images and ARMv7 signing keys, and keeps existing Podman image tags intact. --no-cache refreshes the package layer; the Alpine repository can change between builds.

The private recovery composer and P105 hardware and CLI support follow in separate contributions. Firmware and calibration remain owner-supplied.

Validation:

• The exact base topic passed 56 tests with the published hardware and CLI v0.1.10 pair on Ubuntu 24.04 ARM64, Python 3.9 and 3.12.
• A separate fork workflow checked out the exact proposed commit and ran the PR's test steps on GitHub-hosted Ubuntu 24.04 x86-64. All 56 tests passed on Python 3.9 and 3.12 with the published v0.1.10 dependency pair.
• A direct --no-cache build produced a receipt matching the exported archive. Its 44 package identities and payload hashes matched the fresh P105 integration base; the previously existing Podman tag retained its image ID.
• A separately composed recovery at Minimal 5b9d415, using a fresh base with matching package identities and payload hashes, booted on an iPad mini 1 Wi-Fi. After a one-shot NFS handoff, the same boot reached the desktop. The owner checked display, touch, Home, keyboard, Calculator, Wi-Fi and Bluetooth mouse movement.
• The recovery logged an early initial-console warning. The desktop logged rejected touch-frame reads, so touch remains partial. The first handoff timed out at 120 seconds and reached readiness afterward. A separate local CLI change passed its tests and completed a second handoff using the initialized desktop root.

Merged, thanks. Before merging we renamed p105/ to armv7/, since the base works for every 32-bit board, and changed the receipt's architecture to armv7, Alpine's name for it. Your follow-up contributions should use the new path.
