feat(earn): add distributions table component and tests

[precious-akpan]

Closes #308

Summary

Added the DistributionsTable component to render reward distributions and integrated it into the DistributionsTab.

Details

• Created the extractable DistributionsTable component with typed status variants (distributed, pending, upcoming, claim, claimed).
• Integrated an onClaim interactive callback for claimable epochs.
• Replaced the inline table in distributions-tab.tsx with this extractable component to eliminate duplicated types and styling maps.
• Included the lockfile fix (bun.lock) and test runner fixes to ensure vitest passes properly.
• Added comprehensive unit tests in distributions-table.test.tsx.
