fix: resolve time crate compile error under source-azure feature

[Copilot]

azure_blob.rs referenced time::OffsetDateTime directly, but the time crate is only gated behind provider-azure — not source-azure. Building with --features source-azure alone produced:

error[E0433]: failed to resolve: use of unresolved module or unlinked crate `time`
  --> crates/recoco-core/src/ops/sources/azure_blob.rs:51:29

Change

• azure_blob.rs: Replace bare time::OffsetDateTime with azure_core::time::OffsetDateTime, which re-exports the same type via the azure_core dep already required by source-azure.

// before
fn datetime_to_ordinal(dt: &time::OffsetDateTime) -> Ordinal {

// after
fn datetime_to_ordinal(dt: &azure_core::time::OffsetDateTime) -> Ordinal {

No feature definitions or new dependencies required.

Pull request overview

Fixes a --features source-azure build failure in recoco-core by removing a direct dependency on the time crate from the Azure Blob source implementation and instead using the azure_core re-export already enabled by source-azure.

Changes:

• Switch datetime_to_ordinal to accept azure_core::time::OffsetDateTime instead of time::OffsetDateTime.

• dt.unix_timestamp_nanos() is (effectively) an i128 nanosecond count; casting to i64 before dividing can truncate/overflow for out-of-range timestamps. To avoid incorrect ordinals, do the division in the wider type first (or use a checked conversion) and only then cast to i64 (similar to amazon_s3.rs’s (as_nanos() / 1000) as i64).

fn datetime_to_ordinal(dt: &azure_core::time::OffsetDateTime) -> Ordinal {
    Ordinal(Some(dt.unix_timestamp_nanos() as i64 / 1000))
}
