fix: CI build errors + simplify cache handler and data cache

- Remove `export const dynamic` from 4 routes (incompatible with cacheComponents)
- Static import for redis-handler (Turbopack can't resolve relative dynamic imports)
- Simplify redis-handler: Buffer.concat, NonNullable, single connect promise
- Inline single-use helpers in integration-data-cache
- Non-greedy SVG regex to prevent ReDoS
- Inline getDevelopmentServiceAliases in next.config
- Remove restating comments
