Removes now-unreachable #ifdef _WIN32 branches across Common/ and the three
server binaries (all builds are Linux-only), deletes the entirely unused
SEH exception-handling shim and an orphaned vendored MySQL client header.
Enables LTO and -march=x86-64-v2 in Release builds for a small free perf win.
Also seeds a default GM account (gmadmin/changeme) via
database sql files/gm_account.sql so a fresh deploy has something to log
into the web admin panel with, switches the MariaDB data directory from a
Docker named volume to a host bind mount for visibility/backup, and expands
the README with a fuller Docker deployment walkthrough.

accounts.lastlogin/logtime had no defaults and were NOT NULL, but the
auto-create-account INSERT never set them, so new accounts failed
under MariaDB strict mode (silently accepted under the old MySQL
5.0 target). Insert explicit empty/zero values and give lastlogin a
default; also widen it to varchar(32) to match the runtime.sql fix
already applied to the starttime column.
