fix(service-terraform): truncate long .tfvars file paths in popover

[RemiBonnet]

Summary

Issue:

Long .tfvars file paths in the "Add and order .tfvars files" popover were rendered without any truncation, so a long path overflowed its row, broke the grid layout and pushed the order input out of view.

Changes

• Add min-w-0 to the row's flex container and label so flex/grid children can shrink below their content width.
• Apply truncate to the file source path.
• Wrap the path in a Tooltip so the full path is still readable on hover (consistent with the SourceCell pattern in terraform-variables-table).

Screenshots / Recordings

UI-only change; before/after to be attached by reviewer.

Testing

• Changes tested locally in the relevant Console's pages and Storybooks
• yarn test
• yarn format
• yarn lint

Note: automated checks could not be run in the agent environment (no Node/Yarn toolchain available). Please run yarn format && yarn lint && yarn test in CI/locally.

PR Checklist

• Conventional Commit title with scope
• Self-review performed, diff kept focused
• Designer validation for UI change
