Support scripting collation on database objects and add option to ignore collation

[zacateras]

Add support in the CLI tool to handle scripting of collation definitions on database objects. Users should be able to choose whether collation clauses are included in the generated scripts.

• Add an option to the sqlct.config.json configuration file (e.g., "ignoreCollation": true) to allow users to skip scripting collation when enabled.
• No command-line switch should be implemented as part of this task. Only the config file option should be supported for enabling/disabling collation scripting.
• By default, collation should be preserved to match the source database unless the ignore option is specified in the configuration.
• Update documentation, sample config, and any schema to reflect this new option.
• Cover relevant scenarios in unit/integration tests.

Acceptance Criteria:

• Collation clauses are scripted by default in supported DDL outputs.
• Suppressing collation scripting via the config file works correctly for all supported object types.
• Documentation and config file help reflect this new option.
