`@table(eviction: N)` disables eviction

[ldt1996]

Bug Summary

setTTLExpiration({ eviction: N }) produces NaN cleanupInterval, eviction scanner never starts

Reproduction Repository (if applicable)

https://github.com/HarperFast/harper-qe-logbook/tree/main/v4-to-v5/upgrade-test-component

Steps to Reproduce

(local reproduction steps, not related to the component posted above, but same mechanism)

1. Define a table with @table(database: "demo", eviction: 5) (no expiration: field), or call Table.setTTLExpiration({ eviction: 5 }) directly
2. Write a record: Table.put('a', {}, { expiresAt: Date.now() + 100 })
3. Wait 200ms
4. Table.primaryStore.getSync('a'), record still present
5. describe_all shows "expiration": "NaNs" on the table

Expected Behavior

Records evict after their expiresAt. describe_all shows "expiration" in seconds.

Actual Behavior

Records persist indefinitely. describe_all shows the literal string "NaNs".

Platform
