fix: resolve all syntax errors in provisioning modules

Fixed 29 syntax errors across 4 modules:
- servers/ (6 files, 13 errors): Fixed parentheses in PROVISIONING_ARGS expressions
- taskservs/ (4 files, 6 errors): Fixed parentheses in string interpolation
- main_provisioning/ (3 files, 3 errors): Fixed environment variable access
- lib_provisioning/utils/ (2 files, 2 errors): Fixed standalone env access

Pattern fixed:
- $"($env.PROVISIONING_ARGS? | default "") " → $"(($env.PROVISIONING_ARGS? | default "")) "
- $env.PROVISIONING_ARGS? | default "" → ($env.PROVISIONING_ARGS? | default "")

All modules now have valid Nushell syntax for proper parsing.
