docs: Update documentation for Types, Wrappers, and Configuration

This commit updates several guide files to reflect recent API additions
and improvements across the library.

Types and DSL:
- Documented Types.type/1, Types.validate/2, and Types.coerce/2 helpers.
- Added documentation for the optional coerce_rule/0 and custom_rules/0
  callbacks when defining custom type modules.

Wrappers and Adapters:
- Documented the create_wrapper_factory/2 function which allows for the
  creation of reusable wrapper templates.

Configuration and Settings:
- Added documentation for error_format and allow_population_by_field_name
  fields in the settings schema.

Error Reporting:
- Updated formatting and descriptions for the reporting APIs to improve
  readability and detail coverage.
