Add PostCodeDataVersion to the persisted data

Commit `06b1dbe9c768adf8921e4c1cb915538486b5a7ca` changed the
serialized format of `PostCodeData` without providing backward or
forward compatibility.

Previously, persisted data was stored as a `uint64_t`, whereas the
updated code now expects a `vector<uint8_t>`. When the new code
attempts to deserialize old data, Cereal interprets the `uint64_t`
value as the vector size, resulting in excessively large allocations
and out-of-memory errors during BMC initialization.

This commit introduces a `PostCodeDataVersion` field in the serialized
file. On startup, `post-code-manager` checks this version before
deserialization and discards outdated data if the version does not
match, ensuring a clean start without triggering memory issues.

Tested:
Verified that legacy persisted data is detected and discarded, allowing
`post-code-manager` to initialize with fresh data. No out-of-memory
conditions observed.
