WalkthroughBilling events and the collector now carry an optional tenant_id; Prometheus sample extraction groups samples by tenant and instantiates per-tenant collectors. StorageMetadata gained optional billing fields and TenantMetadata received read/update APIs for those fields. Changes

- Around line 1397-1402: Replace the hardcoded string "DEFAULT_TENANT" with the
shared constant from crate::parseable: import or reference
crate::parseable::DEFAULT_TENANT and use it in the closure inside the filter on
sample.labels.get("tenant_id") so the tenant_id extraction uses DEFAULT_TENANT
instead of the literal; update the filter to compare against DEFAULT_TENANT
(e.g., .filter(|t| *t != DEFAULT_TENANT)) while keeping the surrounding logic
that maps to Option<String>.

In `@src/tenants/mod.rs`:
- Around line 66-83: The update_tenant_meta function currently overwrites
tenant.meta fields with whichever Option<String> values are passed, clobbering
existing metadata when callers pass None; change the logic in update_tenant_meta
so that for each incoming parameter (customer_name, start_date, end_date, plan)
you only assign to tenant.meta.<field> when the corresponding Option is
Some(value) and leave the existing value untouched when it is None, and if you
need to support explicit clearing distinguish "unset" vs "clear" at the API
boundary by using Option<Option<String>> instead.

Verify each finding against the current code and only fix it if needed. In `@src/tenants/mod.rs` around lines 66 - 83, update_tenant_meta currently overwrites existing metadata with None when callers omit fields; change the implementation so it only mutates tenant.meta fields when the corresponding parameter is Some(value) (or alternatively change the function signature to accept Option<Option<String>> at the API boundary to distinguish "not provided" vs "clear"), i.e., locate update_tenant_meta and the assignments to tenant.meta.customer_name, tenant.meta.start_date, tenant.meta.end_date, tenant.meta.plan and replace them with conditional updates that only set the stored field when the incoming parameter is Some(...) (or adapt callers to supply Option<Option<String>> and handle None/Some(None)/Some(Some(val)) accordingly).
