Add option to ignore scripting permissions in sqlct.config.json

[zacateras]

Add a new feature to allow users to ignore scripting of database object permissions via an option in the sqlct.config.json configuration file (for example, "ignorePermissions": true).

• When enabled, permission-related statements (e.g., GRANT, DENY, REVOKE) should be omitted from the generated output.
• By default, permissions should be scripted to match the source database unless the ignore option is set in the configuration.
• Update documentation, the sample config, and schema to reflect this new option.
• Add appropriate unit and integration tests to verify config-driven control of permission scripting.

Acceptance Criteria:

• Permissions are scripted by default unless disabled via the config file.
• Suppressing permission scripting via the config file works for all supported object types.
• Documentation and config help reflect this option.
