* feat(tier): add transition candidate probe contract
Add a fail-closed WarmBackend probe contract for provider-authoritative transition candidate state. Default providers report Unsupported, while the shared mock backend can now model missing, unversioned, and exact-version candidates for follow-up recovery tests.
This is a forward-compatible foundation for #1352/#1358 recovery work and does not change production cleanup behavior.

* feat(tier): probe transition candidates from providers
Implement provider-authoritative transition candidate probing for S3-family warm backends by querying ListObjectVersions with exact-key filtering and fail-closed classification for delete markers, multiple versions, truncation, and unknown versioning state.
This keeps non-S3 providers on the default Unsupported probe result and forwards MinIO, RustFS, and R2 through the S3 probe implementation.

* fix(ecstore): remove reachable panics in tiering, replication, and heal paths
- Parse x-amz-expiration leniently in tier PUT responses; any lifecycle
rule on the remote tier bucket returns an RFC1123 date that the previous
ISO8601 unwrap turned into a panic of the ILM transition worker
- Skip invalid user-metadata header values (with a warning) when building
tier and replication PUT headers instead of panicking on non-ASCII input
- Heal: tolerate absent data_dir for delete markers and remote objects
- transition_object: don't unwrap version_id on unversioned buckets when
recording partial writes for offline disks
- Admin server info: use port_or_known_default() so default-port (80/443)
endpoints don't panic is_server_resolvable
- Tier ListObjectsV2 client: decode response body with from_utf8_lossy
- walk_internal: log merge_entry_channels errors instead of dropping them

* fix(ecstore): fail heal explicitly when data_dir is missing
Address review feedback: unwrap_or_default() silently substituted a nil
UUID when latest metadata lacked data_dir. Delete markers and remote
objects legitimately have no data_dir and skip the data-heal block, but
for a regular object a missing data_dir means corrupt metadata — return
FileCorrupt with a descriptive log instead of building part paths under
a nil UUID directory.

This commit introduces a significant reorganization of the project structure to improve maintainability and clarity.
Key changes include:
- Adjusted the directory layout for a more logical module organization.
- Removed unused crate dependencies, reducing the overall project size and potentially speeding up build times.
- Updated import paths and configuration files to reflect the structural changes.
