Param validation fails for bare placeholders in URLs (`Routine.validate_parameter_usage`)

[alex-w-99]

Parameter validation regex requires quotes around placeholders, so bare placeholders in URLs like https://example.com/?q={{query}}&paramtwo=2 aren't detected as "used" and cause validation errors.

The pattern r'(?:"|\\")\{\{([^}"]*)\}\}(?:"|\\")' needs to also match unquoted {{param}} patterns.

	# Find all parameter usages in the JSON: *"{{*}}"*
	# Match quoted placeholders: "{{param}}" or \"{{param}}\" (escaped quotes in JSON strings)
	# \"{{param}}\" in JSON string means "{{param}}" in actual value
	# Pattern REQUIRES quotes (either " or \") immediately before {{ and after }}
	param_pattern = r'(?:"|\\")\{\{([^}"]*)\}\}(?:"|\\")'
	matches = re.findall(param_pattern, routine_json)
