<!--
Please submit this PR as a draft initially.

Do not mark it as "Ready for review" until this PR meets the canonical
Definition of Ready For Review in `docs/readme/ready-for-review.md`.

In short: the template must be materially complete (not just section
titles
present), all status checks must be currently passing, and the only
expected
follow-up commits must be reviewer-driven.
-->

## **Description**

<!--
Write a short description of the changes included in this pull request,
also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?
-->

This PR updates some strings in the Rewards tab. Some of these strings
were incorrect or didn't convey enough information. The legal disclaimer
was particularly off-base, as well as the campaign end strings.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`
2. Label with `no-changelog`

If this PR is End-User-Facing, please write a short User-Facing
description in the past tense like:
`CHANGELOG entry: Added a new tab for users to see their NFTs`
`CHANGELOG entry: Fixed a bug that was causing some NFTs to flicker`

(This helps the Release Engineer do their job more quickly and
accurately)

## **Pre-merge author checklist**

<!--
Every checklist item must be consciously assessed before marking this PR
as
"Ready for review". A checked box means you deliberately considered that
responsibility, not that you literally performed every action listed.

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
checklist
semantics.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Low-code-risk (copy-only) change, but it updates user-facing
legal/disclosure language and campaign messaging, which may require
careful product/legal review for accuracy and compliance.
> 
> **Overview**
> Updates Rewards English copy in `locales/languages/en.json`, including
a new onboarding description, a revised legal disclaimer ("Terms of Use"
+ clearer disclosure about opting in all device accounts and tracking
onchain activity), and clearer campaign-related messaging (load error
text and end/results banners switching from *contest* to *campaign*
wording).
