Drop era5_batch global_limit — tracker leaks across deploys
The Pro Smart engine's global_limit tracker is stored inside
oban_producers.meta and is not reliably released when a pod exits
between job start and completion. After today's rollout two pods died
holding tracked slots for running era5_batch jobs; the survivors refused
to start any new ones because the cluster-wide tracker was stuck at
4/4 — with zero actual jobs executing — and the whole backfill froze
for 2+ hours.

Keeping rate_limit (10/hr) is enough to stay polite to Copernicus CDS.
local_limit stays at 2 per pod, so effective cluster concurrency just
scales with replica count instead of being capped by a global value
whose bookkeeping can't survive a restart.

# config/runtime.exs is executed for all environments, including
# during releases. It is executed after compilation and before the
# system starts, so it is typically used to load production configuration
# and secrets from environment variables or elsewhere. Do not define
# any compile-time configuration in here, as it won't be applied.
# The block below contains prod specific runtime configuration.
# ## Using releases
#
# If you use `mix release`, you need to explicitly enable the server
# by passing the PHX_SERVER=true when you start it:
#
# PHX_SERVER=true bin/microwaveprop start
#
# Alternatively, you can use `mix phx.gen.release` to generate a `bin/server`
# script that automatically sets the env var above.

# ## SSL Support
#
# To get SSL working, you will need to add the `https` key
# to your endpoint configuration:
#
# config :microwaveprop, MicrowavepropWeb.Endpoint,
# https: [
# ...,
# port: 443,
# cipher_suite: :strong,
# keyfile: System.get_env("SOME_APP_SSL_KEY_PATH"),
# certfile: System.get_env("SOME_APP_SSL_CERT_PATH")
# ]
#
# The `cipher_suite` is set to `:strong` to support only the
# latest and more secure SSL ciphers. This means old browsers
# and clients may not be supported. You can set it to
# `:compatible` for wider support.
#
# `:keyfile` and `:certfile` expect an absolute path to the key
# and cert in disk or a relative path inside priv, for example
# "priv/ssl/server.key". For all supported SSL configuration
# options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1
#
# We also recommend setting `force_ssl` in your config/prod.exs,
# ensuring no data is ever sent via http, always redirecting to https:
#
# config :microwaveprop, MicrowavepropWeb.Endpoint,
# force_ssl: [hsts: true]
#
# Check `Plug.SSL` for all available options in `force_ssl`.
# ## Configuring the mailer
#
# In production you need to configure the mailer to use a different adapter.
# Here is an example configuration for Mailgun:
#
# config :microwaveprop, Microwaveprop.Mailer,
# adapter: Swoosh.Adapters.Mailgun,
# tls: :always + explicit tls_options is required — SMTP2GO's endpoint sits
# behind a wildcard cert (*.smtp2go.com) so SNI is mandatory, and gen_smtp
# won't set it without explicit server_name_indication. Without this, the
# handshake fails with an "unexpected_message" TLS alert.
