centralize action controls and styles in AllDataSelection

[CamilleGuillory]

PR to fix this alignment issue:

Describe your changes

• Introduce reusable action helpers (actionWrapper, actionLink, actionButton) with shared SLDS classes
• Replace repeated anchor/button markup with helpers for deploy status, package.xml, flow tools, and API action buttons
• Wrap actions in a dedicated container (sfir-all-data-actions)

Why: Reduces duplicated JSX, enforces consistent styling/attributes (e.g., target/data-target-link), and simplifies future maintenance of action buttons.

@tprouvot ready for review.
Note: the GitHub file diff looks weird. The changes are easier to understand when viewed locally.
