Enlarge Runbook input fields to support longer text entries

Runbook input fields currently present as small, single-line text boxes with a limited character capacity, which restricts the amount of detail a user can enter when populating fields for integrations, such as third-party change request systems that support longer text entries. This enhancement would enlarge the input field display to span multiple rows and increase the supported character limit to align with common third-party field capacities. Customers would gain the ability to enter detailed implementation plans, justifications, and other extended information directly within Runbook inputs without truncation or workaround.
