Proposed change

Re-bump py-opendisplay from 5.9.0 to 7.2.3. The previous bump to 7.0.0 (#171088) was reverted in #171477 due to Alpine/musl build failures caused by two upstream issues, both now fixed:

1. pyrefly (a Rust-compiled type checker) was accidentally included as a runtime dependency by PyCharm, pulling in a Rust toolchain requirement on source builds.
2. epaper-dithering (transitive dep) had no musllinux_1_2_x86_64 wheel on PyPI, forcing Alpine builders to compile Rust from source.
