fix(dar): format Data Access Request expiry as a date in the task tab

[anuj-kumary]

What & why

On the entity Activity Feed & Tasks tab, a Data Access Request's Expiration Date was shown as a raw epoch number (e.g. 1786699421850), while the DAR detail drawer showed the same value as a friendly date. The task tab renders the DAR payload generically via TaskPayloadSchemaFields, applying per-field DAR_FIELD_FORMATTERS — that map formatted duration but had no entry for expirationDate, so the number fell through unformatted.

How

Add an expirationDate entry to DAR_FIELD_FORMATTERS that reuses the existing shared formatDate util (the same one the DAR detail drawer uses), so both surfaces render the expiry consistently.

Issue -

Testing

• Open a table → Activity Feed & Tasks → a Data Access Request task: the Expiration Date now renders as a date, matching the DAR detail drawer.
• Prettier/tsc clean.
