Configure the locale fallback before Bash starts.

~/.bashrc runs after Bash initialization. An invalid inherited locale can therefore produce a setlocale warning before shell-init.sh clears it. Set the fallback in the container environment or in a wrapper that runs before Bash.

In @.devcontainer/post-create.sh at line 77, Update the post-create setup so the
locale fallback is configured before Bash initialization, rather than only
sourcing shell-init.sh from ~/.bashrc; use the container environment or an
earlier shell wrapper while preserving the existing WORKSPACE_ROOT and
shell-init.sh setup.

Validate every locale override, not only LANG.

When LANG is valid but LC_CTYPE, LC_TIME, or LC_ALL is unsupported, line 9 skips the fallback and leaves the invalid variable in the environment. The warning can continue. When only LANG is invalid, lines 10-11 also remove a valid LC_ALL override. Check locale variables in precedence order and clear or replace only unsupported values.

In @.devcontainer/shell-init.sh at line 9, Update the locale validation logic in
the shell initialization flow to check LC_ALL, each LC_* override, and LANG in
precedence order, rather than validating only LANG. Clear or replace only
variables whose values are unsupported, preserve valid higher-precedence
overrides, and retain the existing warning behavior.
