ref(transport): Log a warning when dropping envelopes due to rate-limiting

[rwachtler]

📜 Description

• Raise the level of an existing log statement which indicated that all envelope items were rate-limited, to SENTRY_LOG_WARN.
• Introduce a new log statement which will log a warning each time an envelope item has been dropped due to an exceeding rate-limit.
• Update clang-formatter to 19.1.2
  • When trying to commit I've got following error:
    • clang-format version mismatch, expected: 19.1.1, but found: 19.1.2. Please run make init to update your local dev tools. This may actually upgrade to a newer version than what is currently recorded in the lockfile; if that happens, please commit the update to the lockfile as well.
    • Tried to resolve via make init, but then followed This may actually upgrade to a newer version than what is currently recorded in the lockfile; if that happens, please commit the update to the lockfile as well.
  • It looks like pre-commit, python and mobile-dev-inc/tap/maestro got updated as well, but since those weren't crucial for the commit, I didn't stage/commit those changes.

In case a pattern of "RateLimit [error-description]" has to be followed, that would be my alt suggestion: RateLimit is active for current envelope item, dropping...
