fix: redundant rebuild trigger on every keystroke in editor containers

Closes #779

Changes

• Removed redundant setTemplateMarkdown(val) function call inside handleChange in TemplateMarkdown.tsx.
• Removed redundant setModelCto(value) function call inside handleChange in TemplateModel.tsx.
• Removed redundant setData(value) function call inside handleChange in AgreementData.tsx.

Flags

• The editor components previously triggered rebuilds twice on every keystroke because useUndoRedo already syncs to the main state internally. This fix ensures each keystroke triggers only a single rebuild. No behavioral changes to state management; just removing the duplication.
