[SC-15827] Document configurable attachment upload limits

[cachafla]

Pull Request Description

What and why?

Updates attachment guidance for records and artifacts to replace the outdated fixed 50 MB limit with the new 100 MB default. The copy also directs readers to the limit shown in ValidMind because deployments can configure a different maximum.

This addresses SC-15827 and keeps the field-type reference consistent with the upload guides.

How to test

Rendered the affected pages locally with Quarto using the development profile:

• guide/inventory/edit-inventory-fields.qmd
• guide/validation/update-artifacts.qmd
• guide/inventory/manage-inventory-fields.qmd
• guide/validation/manage-artifact-fields.qmd

All four pages rendered successfully. The existing unresolved validmind/validmind.qmd link warnings remain unrelated to this change.

What needs special review?

Please confirm that describing 100 MB as the default, while deferring to the limit shown in-product for configured deployments, matches the final behavior in the frontend fix.

Dependencies, breaking changes, and deployment notes

Depends on validmind/frontend#2457. The documentation should merge and deploy with or after the frontend behavior.

No breaking changes or special documentation deployment steps.

Release notes

Updated attachment upload guidance to document the new 100 MB default and clarify that the maximum can vary by deployment. Learn more about managing record attachments.

PR Summary

This PR updates the instructional text for file attachment size limits across several guide files. The previous hard-coded limit of 50 MB has been replaced with a default limit of 100 MB per file. Additionally, the revised messages now indicate that the limit displayed in the user interface (using {{< var vm.product >}}) may vary based on the deployment configuration. These changes are applied in multiple files, including inventory and artifact management guides, to ensure consistency and clearer communication to the user.

The changes focus solely on the user-facing text and do not affect the underlying functionality or file upload mechanisms.

Test Suggestions

• Check that the updated messaging is correctly displayed on the inventory attachments page.
• Verify the artifact attachments documentation shows the new text indicating 100 MB as the default limit.
• Test the dynamic display of deployment-specific limits using the {{< var vm.product >}} variable.
• Ensure that no unintended formatting issues occur in both HTML and revealjs formats.
