json_escape() returns a fully-quoted JSON string (e.g. "value") via
Python's json.dumps(). Callers using printf templates were wrapping
the result in additional quotes ("%s"), producing invalid JSON like
""value"". Remove the redundant quotes from all printf format strings
so json_escape's quotes are used directly.

- Fix triple-quote injection in SSH keys (Scaleway, UpCloud), userdata
(BinaryLane), init scripts (Civo, Kamatera), and GraphQL queries
(RunPod) by passing data via stdin/json_escape instead of inline
string interpolation
- Add input validation for all cloud provider env vars (region, type,
plan, etc.) using validate_region_name/validate_resource_name to block
shell metacharacters before they reach Python string interpolation
- Validate Modal image name as Python identifier to prevent code injection
- Validate numeric env vars (RAM, GPU count, disk size) across all providers
Affects: 19 cloud provider lib/common.sh files
