Learning: In this repository, new translation keys should be added to packages/i18n/src/locales/en.i18n.json only; other locale files are populated via the external translation pipeline and/or fall back to English. Do not request adding the same key to all locale files in future reviews.

In @.changeset/young-humans-stare.md:
- Around line 2-3: The changeset currently marks '@rocket.chat/models' and
'@rocket.chat/meteor' as 'patch' but the addition of a TTL index is a
data-destructive feature and must be surfaced as at least a 'minor' (or 'major')
bump; update the .changeset entry to use 'minor' (or 'major' if you prefer the
stronger signal) for those package entries so releases and release notes
highlight the automatic one‑year expiry change and operators are warned.

The
rocketchat_statisticscollection grows indefinitely as statistics are collected daily but never cleaned up.Customer reported: After running since 2017 (~7 years), their statistics collection reached 496MB - larger than their messages collection (454MB).
Proposed changes (including videos or screenshots)
This PR adds a MongoDB TTL index to automatically expire statistics documents after 1 year (365 days), capping storage to approximately ~70MB regardless of how long the server runs.
Why TTL index?
Issue(s)
Steps to test or reproduce
db.rocketchat_statistics.getIndexes(){ "key": { "createdAt": 1 }, "name": "createdAt_1", "expireAfterSeconds": 31536000 }Further comments
Alternatives considered:
Important: in the future, when we reach the next major, we should merge PR #38572. It contains the index consolidation and a migration that we can’t merge right now, since migrations are only included in major releases. The work there is ready to go.
