Modal

- Added support for mounting Volume or CloudBucketMount storage in `Image.run_function`. Note that this is *typically* not necessary, as data downloaded during the Image build can be stored directly in the Image filesystem.

- It is now an error to create or lookup Modal objects (`Volume`, `Dict`, `Secret`, etc.) with an invalid name. Object names must be shorter than 64 characters and may contain only alphanumeric characters, dashes, periods, and underscores. The name check had inadvertently been removed for a brief time following an internal refactor and then reintroduced as a warning. It is once more a hard error. Please get in touch if this is blocking access to your data.

- The `modal app list` command now reports apps created by `modal app run` or `modal app serve` as being in an "ephemeral" state rather than a "running" state to reduce confusion with deployed apps that are actively processing inputs.

- All modal CLI commands now accept `-e` as a short-form of `--env`

- Added support for entrypoint and shell for custom containers: `Image.debian_slim().entrypoint([])` can be used interchangeably with `.dockerfile_commands('ENTRYPOINT []')`, and `.shell(["/bin/bash", "-c"])` can be used interchangeably with `.dockerfile_commands('SHELL ["/bin/bash", "-c"]')`

- Fix an issue with `web_server` decorator not working on image builder version 2023.12
