fix(wire-format): flip meshkit JSON tags to canonical camelCase (Phase 7c)

Per the ecosystem-wide identifier-naming contract (camelCase on the wire,
snake_case in the database, ORM is the boundary — see
meshery/schemas/AGENTS.md), flip all snake_case `json:` tags on wire-facing
meshkit types to camelCase. `db:` tags are preserved as snake_case; `yaml:`
tags on config structs are preserved as their existing snake_case (yaml
files are user-facing config, not a Meshery API wire contract).

The meshkit Event type is the load-bearing change: it is embedded into
meshery-cloud's EventResult and meshery server's events stream, so its
snake_case keys (acted_upon, user_id, system_id, created_at, ...) were
leaking out of every downstream API even after Phase 4 flipped the
local cloud types. With this change, every meshkit-emitted event field
is camelCase end-to-end.

Files flipped:
- models/events/events.go               (11 tags: actedUpon, userId,
                                         systemId, operationId, createdAt,
                                         updatedAt, deletedAt; plus the
                                         four EventsFilter tags sortOn,
                                         actedUpon, userId, systemId)
- models/catalog/v1alpha1/catalog.go    (4 tags: contentClass,
                                         publishedVersion, patternCaveats,
                                         patternInfo)
- database/database.go                  (3 tags: createdAt, updatedAt,
                                         deletedAt on the shared Model)
- tracing/tracing.go                    (2 tags: serviceName,
                                         serviceVersion — yaml: kept
                                         snake_case for config files)
- utils/kubernetes/kubernetes.go        (1 tag: dynamicKubeClient)
- models/smi_conformance.go             (1 tag: mesheryId)
- generators/github/package.go          (1 tag: sourceUrl)

Docs updated:
- docs/event-streaming.md excerpt updated to reflect camelCase JSON tags
  on the canonical Event struct.

Explicitly excluded (NOT flipped) per scope:
- cmd/errorutil/internal/{component,error}/*.go — internal output schema
  for the errorutil tool (consumed by CI / `make error`); not a wire
  contract.
- utils/walker/github.go — github API mirror; 3rd-party wire contract.
- utils/csv/csv_test.go — `person_age` is a CSV column header in a test
  fixture, not a json wire contract.

Cross-repo follow-ups required after meshkit releases a tag containing
this change:
- meshery: bump go.mod meshkit dep; UI consumers of /api/system/events
  must read camelCase (actedUpon, userId, systemId, createdAt, ...).
- meshery-cloud: bump go.mod meshkit dep; the embedded Event in
  EventResult now emits camelCase, so the cloud UI events table must
  read camelCase.
- meshery-extensions: bump go.mod meshkit dep; verify catalog/event
  surfaces.

Verification:
- `go build ./...` clean
- `go vet ./...` clean
- `go test -count=1 ./...` all packages pass
