[3/7] Remove `t` Prop Drilling in Tag and Organization Components

[kushu30]

Context

As part of the repository-wide translation compliance cleanup (post #7364), this batch addresses Tag and Organization-related components that are currently passing t as a prop/parameter instead of calling useTranslation() locally.

This batch is domain-scoped to keep refactors reviewable and reduce merge conflicts.

---

Affected Files

Tag-related:

• src/components/AdminPortal/TagActions/TagActions.tsx
• src/components/AdminPortal/TagActions/Node/TagNode.tsx
• src/screens/AdminPortal/ManageTag/editModal/EditUserTagModal.tsx
• src/components/AdminPortal/AddPeopleToTag/AddPeopleToTag.tsx

Organization-related:

• src/components/AdminPortal/OrgList/modal/OrganizationModal.tsx
• src/screens/AdminPortal/OrgList/OrgList.tsx
• src/screens/UserPortal/Organizations/Organizations.tsx

---

Required Refactor

For each affected file:

• Remove t from component props and parameters
• Eliminate t prop drilling chains
• Import useTranslation from react-i18next
• Call const { t } = useTranslation() locally
• Ensure correct namespace usage
• Update related tests where t was mocked or injected

No UI or functional behavior should change.

---

Acceptance Criteria

• No component in this batch receives t as a prop
• All translation calls originate from local useTranslation()
• Tests pass without flakiness
• No coverage regression
• Translation lint checks pass in CI
• Changes are limited strictly to this domain
