feat(deps)!: migrate from fiber v2 to fiber v3

Browse Source 
BREAKING CHANGE: upgrades the HTTP framework from gofiber/fiber/v2 to gofiber/fiber/v3, and gofiber/websocket/v2 to gofiber/contrib/v3/websocket.

- Handlers now take fiber.Ctx (interface) instead of *fiber.Ctx. - DisableStartupMessage moved from fiber.Config to fiber.ListenConfig on the proxy/api/monitoring Listen calls. - cors AllowOrigins is now []string; c.BodyParser -> c.Bind().Body(). - app.Test takes fiber.TestConfig instead of an int timeout (tests updated). - WebSocket swapped to contrib/v3/websocket (same Conn/New/Config/IsCloseError/IsWebSocketUpgrade API; Conn.Query preserved). - Adopts fasthttp v1.71.0 (pulled by fiber v3), resolving the v1.71 Host-header enforcement that broke the prior pinned-v1.69 workaround.

fix(connpool): the background keep-alive goroutine no longer reads the mutable global cfg (captures HostGraphQL/HealthcheckGraphQL at pool creation). Under v3 timing it raced with parseConfig/test cfg reassignment; go test -race ./... is now clean (0 data races).

test: make the circuit-breaker cache-fallback and request-coalescing integration tests deterministic (cache TTL outlives the retry loop; coalescing asserts against a measured single-request baseline instead of a hard-coded count); drop the flaky timing-ratio assertion in TestTimingAttackResistance (constant-time guarantee comes from subtle.ConstantTimeCompare, not wall-clock timing).

Verified: go build, go vet, golangci-lint (0 issues), go test -race ./... (all packages pass, 0 races), govulncheck (no vulnerabilities). App + dashboard + WebSocket verified live under v3 in single-node and cluster modes.
