chore(billing): Bump sentry-protos to 0.24.0

[dashed]

Summary

Bumps the sentry-protos pin from 0.22.3 → 0.24.0 (latest). This is a routine dependency bump that touches only pyproject.toml and the uv.lock lockfile.

What's included

Going from 0.22.3 to 0.24.0 picks up two billing proto additions:

Version	Change	Upstream
0.23.0	Add optional type to InvoiceLineItem	sentry-protos#293
0.24.0	Add tax_number to BillingDetails	sentry-protos#286

Release: https://github.com/getsentry/sentry-protos/releases/tag/0.24.0

Why

These new proto fields are consumed by in-flight getsentry billing work and need the bump to land in sentry first:

• getsentry#20568 — persist invoice line item type on platform invoices (uses InvoiceLineItem.type, 0.23.0)
• getsentry#20532 — make platform contract invoices tax-inclusive / REVENG-15 (uses tax_number, 0.24.0)
• getsentry#20549 — degrade platform tax on a provider outage and backfill it
• getsentry#20556 — classify Stripe infra errors at the charge seam

Notes

• Lockfile regenerated with uv lock --upgrade-package sentry-protos; only the sentry-protos entry changed (version + wheel URL + sha256).
• Backend-only change; no frontend impact.
