Validate JSON parsed from Redis before trusting cache payloads

[nanaf6203-bit]

Context

redisCache.ts (and propertyCache paths) JSON.parse Redis payloads and cast/return them as Property/SearchResult without schema validation.

Problem

A poisoned or stale cache entry (or partial write) yields malformed objects into UI rendering, potentially causing runtime crashes or injected markup via dangerouslySetInnerHTML-adjacent paths.

Proposed approach

Parse through zod schemas (src/types/property schemas) with a safe fallback to miss/regenerate; log parse failures via structured logger.

Acceptance criteria

• Cached values validated or safely discarded on mismatch
• Parse failure counted in stats/logs
• Unit test with corrupted payload
