fix(frontend): show correct variant name in commit modal for new vari…

[Sanket2329]

Summary

• Added commitModalOriginalEntityNameAtom in state.ts to keep track of the original name of the entity before any user edit overrides.
• Updated EntityCommitTitle.tsx to conditionally display originalEntityName for commit actions.
• Updated EntityCommitContent.tsx to display originalEntityName as the source, and the user-typed entityName as the target (blue text) in the version transition display.
• This resolves issue Commit modal shows wrong variant name for new variants #4670 where the commit modal erroneously displayed the user-typed new variant name as the source name (instead of the original source variant name) when committing as a new variant.

Testing

Verified locally

• Verified locally at http://localhost:3000 by editing a prompt template on the default variant, choosing the "As a new variant" option in the commit modal, and typing in a new variant name. The title, description text, and version transition correctly show default as the source instead of the new target variant name.
• Ran pnpm lint-fix on the web workspace to check formatting.
• Verified TypeScript build check passes successfully on @agenta/entity-ui and @agenta/oss.

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Commit modal now displays the original entity name for version transitions (including create new variants/revisions), ensuring labels and tooltips remain accurate even when names are edited.
  • Commit title and variant/revision target labeling were updated to use the original name where appropriate, improving consistency across the modal’s UI.

Walkthrough

A new derived Jotai atom commitModalOriginalEntityNameAtom is added to state.ts, resolving an entity's display name before any user edits via the entity adapter. The atom is exported through the commit module, modals, and package barrel files. EntityCommitTitle and EntityCommitContent are updated to consume this atom and display the original name in relevant UI text.

Changes

Commit Modal Original Entity Name

Layer / File(s)	Summary
New atom definition and barrel exports src/modals/commit/state.ts, src/modals/commit/index.ts, src/modals/index.ts, src/index.ts	commitModalOriginalEntityNameAtom is defined as a derived atom reading commitModalEntityAtom and resolving the entity's pre-override display name via the adapter, then re-exported through each barrel file up to the package root.
EntityCommitTitle and EntityCommitContent consume original name src/modals/commit/components/EntityCommitTitle.tsx, src/modals/commit/components/EntityCommitContent.tsx	Both components import and read originalEntityName from the new atom. EntityCommitTitle selects between original and current name based on actionLabel. EntityCommitContent uses originalEntityName in version-transition and source-entity labels, and adds an entityName fallback for the variant target label.
