Story: https://linear.app/n8n/issue/PAY-1188
- Implement Redis hashes on the caching service, based on Micha's work
in #7747, adapted from `node-cache-manager-ioredis-yet`. Optimize
workflow ownership lookups and manual webhook lookups with Redis hashes.
- Simplify the caching service by removing all currently unused methods
and options: `enable`, `disable`, `getCache`, `keys`, `keyValues`,
`refreshFunctionEach`, `refreshFunctionMany`, `refreshTtl`, etc.
- Remove the flag `N8N_CACHE_ENABLED`. Currently some features on
`master` are broken with caching disabled, and test webhooks now rely
entirely on caching, for multi-main setup support. We originally
introduced this flag to protect against excessive memory usage, but
total cache usage is low enough that we decided to drop this setting.
Apparently this flag was also never documented.
- Overall caching service refactor: use generics, reduce branching, add
discriminants for cache kinds for better type safety, type caching
events, improve readability, remove outdated docs, etc. Also refactor
and expand caching service tests.

Since crypto-js was
[discontinued](1da3dabf93),
[we migrated all our backend encryption to native
crypto](https://github.com/n8n-io/n8n/pull/7556).
However I decided back then to not remove crypto-js just yet in
expressions, as I wanted to use `SubtleCrypto`. Unfortunately for that
to work, we'd need to make expressions async.
So, to get rid of `crypto-js`, I propose this interim solution.

Once the packages are published to NPM, they don't have the
`pnpm-lock.yaml` to fix dependency versions. Which means that any
dependency with `^` gets auto-upgrade to the latest matching minor,
which can cause issues like
[this](https://github.com/node-cache-manager/node-cache-manager/issues/611).
This change expands on the command channel communication introduced
lately between the main instance(s) and the workers. The frontend gets a
new menu entry "Workers" which will, when opened, trigger a regular call
to getStatus from the workers. The workers then respond via their
response channel to the backend, which then pushes the status to the
frontend.
This introduces the use of ChartJS for metrics.
This feature is still in MVP state and thus disabled by default for the
moment.

This change ensures that things like `encryptionKey` and `instanceId`
are always available directly where they are needed, instead of passing
them around throughout the code.

[PAY-840](https://linear.app/n8n/issue/PAY-840/introduce-object-store-service-and-manager-for-binary-data)
This PR introduces an object store service for Enterprise edition. Note
that the service is tested but currently unused - it will be integrated
soon as a binary data manager, and later for execution data.
`amazonaws.com` in the host is temporarily hardcoded until we integrate
the service and test against AWS, Cloudflare and Backblaze, in the next
PR.
This is ready for review - the PR it depends on is approved and waiting
for CI.

all commands sent between main instance and workers need to contain a
server id to prevent senders from reacting to their own messages,
causing loops
this PR makes sure all sent messages contain a sender id by default as
part of constructing a sending redis client.

Depends on: #7092 | Story:
[PAY-768](https://linear.app/n8n/issue/PAY-768)
This PR:
- Generalizes the `IBinaryDataManager` interface.
- Adjusts `Filesystem.ts` to satisfy the interface.
- Sets up an S3 client stub to be filled in in the next PR.
- Turns `BinaryDataManager` into an injectable service.
- Adjusts the config schema and adds new validators.
Note that the PR looks large but all the main changes are in
`packages/core/src/binaryData`.
Out of scope:
- `BinaryDataManager` (now `BinaryDataService`) and `Filesystem.ts` (now
`fs.client.ts`) were slightly refactored for maintainability, but fully
overhauling them is **not** the focus of this PR, which is meant to
clear the way for the S3 implementation. Future improvements for these
two should include setting up a backwards-compatible dir structure that
makes it easier to locate binary data files to delete, removing
duplication, simplifying cloning methods, using integers for binary data
size instead of `prettyBytes()`, writing tests for existing binary data
logic, etc.

This PR implements the updated license SDK so that worker and webhook
instances do not auto-renew licenses any more.
Instead, they receive a `reloadLicense` command via the Redis client
that will fetch the updated license after it was saved on the main
instance
This also contains some refactoring with moving redis sub and pub
clients into the event bus directly, to prevent cyclic dependency
issues.
