System Test: as a DApp developer, I'm able to bump and restore ledger entries

What problem does your feature solve?

no coverage for js-soroban-client using BumpFootprintExpirationOp and RestoreFootprintOp operations.

What would you like to see?

new test coverage with steps/scenarios that trigger NODEJS(js-soroban-client) to invoke BumpFootprintExpirationOp and RestoreFootprintOpoperations and verify the expected response and outcomes:

• for bumping contract entries to newer expiry ledgers
• for restoring contract entires that were evicted

Identify how expired/evicted contract data entry can be created/initiated on target network under test during the test timeframe for local or remote network usage(testnet, futurenet). Are there networks that it won't be possible?

What is best entry point in javascript for a test to exercise state expirations, test should validate that javascript navigates the expected responses from invoke host fn failing first due to expiry has happened to contract entries, and then ensuing bump/restores done and contract fn invoked succesfully afterwards?

Do we need to create a new contract that is purpose built to enable with testing expiration, i.e. it has state, and can set expiration on it to very small timeframe so test can trigger correct outcomes?

What alternatives are there?

note, this only establishes coverage for js, cli coverage of the same functionality is done in https://github.com/stellar/soroban-tools/blob/main/cmd/soroban-rpc/internal/test/cli_test.go
