Pull request overview

Updates Dapr docs to describe expanded HotReload behavior beyond components/subscriptions, including configuration/resiliency/HTTPEndpoint changes that trigger a graceful sidecar restart.

Changes:

• Adds preview-feature documentation for configuration/resiliency/HTTPEndpoint hot reloading (graceful restart via SIGHUP).
• Adds “Hot Reloading” sections to Configuration and Resiliency overviews.
• Renames “Updating components” doc to “Updating resources” and expands it to cover additional resource types.

• The page is now titled/described as “Updating resources”, but the intro still talks only about updating components and says the sidecar must be restarted to pick up “the latest version of the component”. This is misleading given the later section describing hot reload / SIGHUP restarts for other resource types; consider rewriting the intro to cover resources broadly (and call out the different behaviors for components vs configuration/resiliency/HTTPEndpoints).

When making an update to an existing deployed component used by an application, Dapr does not update the component automatically unless the [`HotReload`](#hot-reloading-preview-feature) feature gate is enabled.
The Dapr sidecar needs to be restarted in order to pick up the latest version of the component.
How this is done depends on the hosting environment.

Grammar: “enabled by via” is redundant; it should be “enabled via …”.

Suggested change

	> Hot reloading is enabled by via the [`HotReload` feature gate]({{% ref "support-preview-features.md" %}}).

The link for “HTTPEndpoint” points to service-invocation-overview.md, which doesn’t mention HTTPEndpoints. Consider linking to the HTTPEndpoint-specific docs (for example the HTTPEndpoint spec/reference page) so readers land on relevant content.

Suggested change

	With the `HotReload` feature gate enabled, the Dapr sidecar also supports reloading [Configuration]({{% ref "configuration-overview.md" %}}), [Resiliency]({{% ref "resiliency-overview.md" %}}), and [HTTPEndpoint]({{% ref "service-invocation-overview.md" %}}) resources.
	With the `HotReload` feature gate enabled, the Dapr sidecar also supports reloading [Configuration]({{% ref "configuration-overview.md" %}}), [Resiliency]({{% ref "resiliency-overview.md" %}}), and [service invocation]({{% ref "service-invocation-overview.md" %}}) (HTTPEndpoint) resources.

In the list of resource types, Configuration and Resiliency are linked but HTTPEndpoint is not. For consistency (and to help navigation), consider linking “HTTPEndpoint” to its reference/how-to page as well.

Suggested change

	Hot reloading also extends to [Configuration]({{% ref "configuration-overview.md" %}}), [Resiliency]({{% ref "resiliency-overview.md" %}}), and HTTPEndpoint resources.
