simplify: use ResolveRequestPageSize helper in eventgateway fetch functions

[Copilot]

PR #865 introduced common.ResolveRequestPageSize(cfg) to encapsulate the repeated page-size resolution pattern but left 8 eventgateway/adopt files using the duplicated 3-line inline block, and getEventGateway.go missing the < 1 fallback guard entirely (risking pageSize=0 sent to the API).

Changes

• 7 eventgateway fetch functions (backend_clusters, virtual_clusters, listeners, data_plane_certificates, schema_registries, static_keys, tls_trust_bundles): replace duplicated inline block with helper
• adopt/event_gateway.go: replace int-typed block + int64() cast with helper (already returns int64)
• getEventGateway.go: fix missing < 1 guard — bare int64(cfg.GetInt(...)) could pass pageSize=0 to the API

// Before (repeated in 7+ files):
requestPageSize := int64(cfg.GetInt(common.RequestPageSizeConfigPath))
if requestPageSize < 1 {
    requestPageSize = int64(common.DefaultRequestPageSize)
}

// After:
requestPageSize := common.ResolveRequestPageSize(cfg)

No functional changes — the helper is a direct extraction of the inline logic.

Pull request overview

This PR refactors Konnect Event Gateway listing/fetching code to use the shared common.ResolveRequestPageSize(cfg) helper, reducing duplicated pagination page-size resolution and ensuring the Event Gateway list call won’t send pageSize=0 when unset/invalid.

Changes:

• Replace repeated inline page-size fallback logic with common.ResolveRequestPageSize(cfg) across Event Gateway fetch functions.
• Update Event Gateway adopt flow to use the shared page-size helper (and remove redundant int/int64 conversions).
• Apply small gofmt/goimports formatting adjustments in a handful of related files.
