* mesh: Update Envoy version to 1.26.7 to address [CVE-2024-23324](https://github.com/envoyproxy/envoy/security/advisories/GHSA-gq3v-vvhj-96j6), [CVE-2024-23325](https://github.com/envoyproxy/envoy/security/advisories/GHSA-5m7c-mrwr-pm26), [CVE-2024-23322](https://github.com/envoyproxy/envoy/security/advisories/GHSA-6p83-mfmh-qv38), [CVE-2024-23323](https://github.com/envoyproxy/envoy/security/advisories/GHSA-x278-4w4x-r7ch), [CVE-2024-23327](https://github.com/envoyproxy/envoy/security/advisories/GHSA-4h5x-x9vh-m29j), and [CVE-2023-44487](https://github.com/envoyproxy/envoy/security/advisories/GHSA-jhv4-f7mr-xx76) [[GH-20586](https://github.com/hashicorp/consul/issues/20586)]
IMPROVEMENTS:
* ProxyCfg: avoid setting a watch on `Internal.ServiceDump` when mesh gateway is not used. [[GH-20168](https://github.com/hashicorp/consul/issues/20168)]
* ProxyCfg: only return the nodes list when querying the `Internal.ServiceDump` watch from proxycfg [[GH-20168](https://github.com/hashicorp/consul/issues/20168)]
* Upgrade to use Go 1.21.7. [[GH-20545](https://github.com/hashicorp/consul/issues/20545)]
BUG FIXES:
* audit-logs: **(Enterprise Only)** Fixes non ASCII characters in audit logs because of gzip. [[GH-20345](https://github.com/hashicorp/consul/issues/20345)]
* connect: Fix issue where re-persisting existing proxy-defaults using `http` protocol fails with a protocol-mismatch error. [[GH-20481](https://github.com/hashicorp/consul/issues/20481)]
* connect: Fix regression with SAN matching on terminating gateways [GH-20360](https://github.com/hashicorp/consul/issues/20360) [[GH-20417](https://github.com/hashicorp/consul/issues/20417)]
* connect: Remove code coupling where the xDS capacity controller could negatively affect raft autopilot performance. [[GH-20511](https://github.com/hashicorp/consul/issues/20511)]
* mesh: Fix bug where envoy extensions could not be configured with "permissive" mTLS mode. Note that envoy extensions currently do not apply to non-mTLS traffic in permissive mode. [[GH-20406](https://github.com/hashicorp/consul/issues/20406)]
