The Oracle Linux based mysql:8.4 image requires x86-64-v2 and fails on the
PESCO Docker host even with the Proxmox CPU type set to host. The Debian
build runs on baseline x86-64; MYSQL_IMAGE still allows overriding.

mysql:8.4 (Oracle Linux 9 build) aborts with 'Fatal glibc error: CPU does
not support x86-64-v2' on generic VM CPU types (kvm64/qemu64) and pre-2009
hardware. MYSQL_IMAGE env var (default mysql:8.4) lets such hosts run the
baseline-x86-64 mysql:8.0-debian build instead.

Without the exec bit the MySQL entrypoint sources the script instead of
executing it, leaking set -euo pipefail into MySQL's own startup shell and
aborting first-time initialization (container exits -> unhealthy -> compose
dependency failure).
