docs: update template naming to reflect team-local names

Template names are now scoped to teams rather than being globally unique.
This updates the documentation to reflect the changes from e2b-dev/infra
PRs #1760 and #1806.

- Update names.mdx to explain team-local naming with namespace format
- Add backwards compatibility note for existing public templates
- Update tags.mdx to show namespaced format examples
- Fix outdated alias parameter in billing.mdx
- Update from_template example in base-image.mdx

-## Uniqueness Requirement
+## Team-Local Naming
 
-<Warning>
-Template names must be **globally unique across the entire E2B platform**, not just within your team or account. This means if another user has already claimed a name, you cannot use it for your template.
-</Warning>
+Template names are scoped to your team. This means:
 
-When choosing a name, consider using:
-- Your company or project name as a prefix (e.g., `acme-api-server`)
-- Version numbers or environment indicators (e.g., `myapp-v2`, `myapp-staging`)
-- Descriptive names that indicate the template's purpose (e.g., `data-analysis-python`)
+- Your template named `my-app` is stored as `your-team-slug/my-app`
+- You can reference it simply as `my-app` within your team
+- Other teams can have their own `my-app` template without conflict
+- Public templates should be referenced using the full namespaced format (`team-slug/template-name`)
+
+<Note>
+**Backwards Compatibility**: Existing public templates remain accessible without the team slug prefix. New public templates should be referenced using the full namespaced format (`team-slug/template-name`).
+</Note>

 1. **Use descriptive names**: Choose names that clearly indicate the template's purpose or configuration
 2. **Use tags for versioning**: Instead of baking version numbers into names, use [tags](/docs/template/tags) for version management (e.g., `myapp:v1`, `myapp:v2`)
