Correct en strings

Correct capitalization, add missing strings

PR Summary

• Standardized Text Capitalization Across Language Files
  For a more uniform look and feel, the text across multiple language files (including English, Arabic, Kurdish, and German) is updated to have capitalized first letters (e.g., "created at" to "Created at", "status" to "Status"). Consistent casing is now also ensured for all references to 'webhook'.

• Refinement of Descriptions
  Various descriptions within the English language files have been refined to enhance the clarity of the text and the qualification of specific terms.

• Addition of Key-Value Pair
  A new key-value pair has been added labelled 'value_help'. This aims to provide additional context for the values stored within the collection language file, resulting in easier understanding and use.

• Improved Consistency and Clarity of the User Interface Text
  In the edit-collection-warning.blade.php view file, the format of a warning message was altered for additional explicitness. Changes were made on additional view files to make sure that user interface texts are clearer, properly capitalized, and match the improved language strings.

• Uniformity in Translated Strings
  Similar updates are made to Spanish and French language files. This ensures translated strings also remain consistent and correctly formatted to match the changes made in other language files.

Hi folks, many of the English strings are incorrectly capitalized, some strings are missing entirely such as "Avatar". This PR corrects the English strings.

There are still more corrections that could be made but these are the ones I was able to spot manually on the dashboard and then manually confirm the changes are correct.
