Bug: Metric Buckets Payload Deserialization Failure
The deserialize_from method stopped parsing metric_buckets payloads as JSON. This means existing envelopes with metric_buckets will now be deserialized as raw bytes, which could cause runtime errors when a parsed object is expected.

### Description Removes `to_timestamp()` and the module-level `epoch` constant from `sentry_sdk/utils.py`. Nothing uses either of them. #4899 (removing the old metrics code) deleted the last three callers of `to_timestamp`, all in `sentry_sdk/metrics.py`, plus its import there. `epoch` was only ever used inside `to_timestamp`. **Evidence** - `grep -rnw to_timestamp sentry_sdk tests scripts` only matches the definition. - `grep -rnw epoch sentry_sdk tests` only matches the definition and its use in `to_timestamp`. The other match is the `(?P<epoch>...)` regex group in the version parser, which isn't related. - `git log -S "to_timestamp(" -- sentry_sdk tests` shows #4899 as the last change to touch a call site. - No open PR diff in this repo mentions `to_timestamp` or `epoch`. **Why it's safe** - `sentry_sdk.utils` is an internal module. Neither name is re-exported from `sentry_sdk` or listed in `docs/`, and neither appears in `CHANGELOG.md` or `MIGRATION_GUIDE.md`. - The helper had a latent bug: it subtracted from a naive `datetime(1970, 1, 1)`, so passing it a timezone-aware datetime (the SDK uses aware UTC datetimes everywhere) raised `TypeError`. Leaving it around invites someone to reuse it by mistake. - `datetime` is still imported and used elsewhere in the module. - No runtime behavior changes. **Checks** - `uv run ruff check sentry_sdk tests` and `ruff format --check` pass. - `uv run --group typing mypy sentry_sdk` passes with no issues. - `TESTPATH="tests/test_utils.py tests/test_basics.py tests/test_client.py" uv run tox -e py3.14-common`: 587 passed, 3 skipped. #### Issues None.
