Added member activity on gift redemption

[sagzy]

ref https://linear.app/ghost/issue/BER-3533

• adds a gift_redemption_event to the member activity feed so that when a member redeems a gift subscription, their timeline shows a dedicated entry:

🎁 Started paid subscription (Ultra) via gift

• the existing gift_purchase_event also adopts the new gift icon so both sides of a gift read consistently in the buyer's and redeemer's member pages

Walkthrough

This pull request adds support for a new gift_redemption_event event type throughout the Ghost admin members event system. Changes include updating icon and action display handling in the event parser, modifying event type toggle logic to treat redemption events alongside payment events, adding a new repository method to query and format gift redemption events from the Gift model with redeemer and tier relationships, and corresponding test coverage for the new event retrieval and filtering behavior.

In `@ghost/admin/app/helpers/parse-member-event.js`:
- Around line 276-279: The gift redemption branch uses event.data.tier_name
directly which can be undefined and produce "(undefined)" in the UI; update the
branch that handles event.type === 'gift_redemption_event' (where const tierName
= event.data.tier_name) to guard against missing/null values by using a fallback
string (e.g., "unknown tier" or omit the tier text) before constructing the
return message so the UI never shows "(undefined)". Ensure you reference the
existing symbol tierName (and the event.type === 'gift_redemption_event' branch)
when applying the change.
