fix(store): error when account sync page cannot make progress

[crazywriter1]

Summary

• Vault and storage-map sync pagination returned an empty page with last_block_included = block_range.start() when a single block exceeded the row limit, so clients could skip that block and permanently lose updates.
• Match the SyncTransactions pattern: return AccountSyncPageExceedsPayloadLimit (RPC out_of_range) when pagination cannot make progress.
• GetAccount storage-map reconstruction maps the new error to LimitExceeded.

Test plan

• cargo test --locked -p miden-node-store --lib all_entries_in
• cargo test --locked -p miden-node-store --lib multi_block_pagination
• cargo test --locked -p miden-node-store --lib paginates_until_last_block
