Make each Coder template self-contained (fix coder templates push failure)

coder templates push -d templates/<env> only uploads that directory to the
Coder server, so main.tf's file() references reaching outside it via
../../profile-templates and ../../scripts failed at push/apply time
("Invalid function argument ... this function works only with files that
are distributed as part of the configuration source code"). Confirmed via
an actual failed run of coder-templates.yml once the runner network fix let
it get that far.

Fix: duplicate profile.code-profile, cli-setup-wizard.sh, and
install-skills.sh into each templates/<env>/ directory and drop the old
shared scripts/ and profile-templates/ directories.
