perf(frontend): add stable pagination and snapshot behavior to transfer history

[arisu6804]

Problem

New transfers arriving during paging can duplicate or omit entries, confusing reconciliation.

Objective

Deliver a production-quality improvement to transfer history pagination and cache that creates measurable value for correctness, security, reliability, performance, or maintainability.

Implementation scope

• Use cursor or snapshot pagination with stable tie-breakers; reset cursors on filter changes; handle expired cursors safely.

Acceptance criteria

• Pages are complete and deterministic for their snapshot; cursor scope is enforced; expired cursors have recovery behavior.

Required validation

• Concurrent-insert, cursor-expiry, filter-reset, and large-fixture tests.
• Existing tests and CI remain passing.
• Add regression coverage for the original failure mode.
• Do not weaken, delete, or skip unrelated tests to obtain a green build.

PR quality bar

• Keep the PR focused and explain design tradeoffs, compatibility impact, and test evidence.
• Avoid typo-only, documentation-only, cosmetic-only, or unrelated refactor submissions.

Out of scope

• Broad rewrites not required by the acceptance criteria.
• Changes to unrelated services, contracts, or user flows.
