Make dialog action buttons width-aware and use concise global labels

[fderuiter]

Summary:

Dialog buttons across the app, including the “Create CT Package” action, overflow their fixed 120 px width when given context‑specific labels. Introduce globally reusable short labels (e.g., “Create,” “Select,” “Save”) and allow SimpleFormDialog buttons to size automatically so future dialogs aren’t constrained by label length.

Rationale:

Ensures consistent UX and readability across all dialogs by preventing label truncation and encouraging a shared vocabulary of concise action texts.

Scope:

• studybuilder/src/components/tools/SimpleFormDialog.vue – make button width responsive or configurable.
• studybuilder/src/locales/en.json – add global action labels and migrate existing dialogs to them.
• All dialog components using SimpleFormDialog – update actionLabel bindings to reference global keys.

References:

• Fixed button width definitions in SimpleFormDialog.vue.
• Context-specific translation keys like CTStandardVersionsForm.create_package that exceed width constraints.

Thanks @fderuiter for this finding. I have shifted this issues to the "Enhancement" discussions.
