fix: use curl+gpg for deadsnakes PPA, arm64 base back to ubuntu:24.04

Browse Source 
Ubuntu 26.04 ships Python 3.14, not 3.13. Reverted arm64 to ubuntu:24.04.
Both architectures now add the deadsnakes PPA by fetching the GPG key via
curl and piping through gpg --dearmor — no gpg-agent, safe under QEMU.
Removes the per-arch conditional and ARG TARGETARCH dependency in RUN commands.

## [Unreleased]
## [0.2.7] - 2026-06-12
### Fixed
- **arm64 base reverted to Ubuntu 24.04**: Ubuntu 26.04 ships Python 3.14, not 3.13 — `python3.13` was not locatable in its repos. Reverted arm64 base to `ubuntu:24.04`.
- **Deadsnakes PPA now uses curl+gpg instead of `add-apt-repository`**: `add-apt-repository` spawns a gpg-agent which crashes under QEMU (arm64 CI). The PPA is now added by fetching the key via `curl` and piping through `gpg --dearmor` — no agent, works on both architectures.
- **PPA conditional removed**: both amd64 (Ubuntu 22.04 CUDA) and arm64 (Ubuntu 24.04) now go through the same deadsnakes install path, eliminating the per-arch branching and the `ARG TARGETARCH` dependency in RUN commands.
