GMATH-3 - Add filter to control merge tag replacement for custom content

[omarkasem]

This update introduces a new filter, gravityview/fields/custom/replace_variables, allowing plugins to modify the behavior of merge tag replacements in custom content. The filter enables developers to prevent merge tags from being replaced before shortcode processing, enhancing flexibility for plugin integrations.

• Added filter to control merge tag replacement in field-custom.php
• Updated logic to conditionally replace variables based on the filter's return value

Summary by CodeRabbit

• New Features
  • Added a configurable filter that lets developers enable or disable automatic merge-tag and variable replacement in custom content fields. Default behavior remains unchanged (replacement on), but replacement can be skipped when desired to support advanced customization and alternative rendering approaches.

Walkthrough

A new filter hook gravityview/fields/custom/replace_variables was added to the custom field template to let callers enable/disable merge-tag/variable replacement. The call to GravityView_API::replace_variables() is now executed only if the filter returns true (default).

Changes

Cohort / File(s)	Summary
Custom Field Filter Hook templates/fields/field-custom.php	Added gravityview/fields/custom/replace_variables filter; introduced $should_replace_variables = apply_filters(..., true) and made GravityView_API::replace_variables() conditional on that flag. Added docblock for the filter and its parameters.
