fix(perf): simplify eventstore queries by removing or in projection handlers (#9530) 
# Which Problems Are Solved

[A recent performance
enhancement]((https://github.com/zitadel/zitadel/pull/9497)) aimed at
optimizing event store queries, specifically those involving multiple
aggregate type filters, has successfully improved index utilization.
While the query planner now correctly selects relevant indexes, it
employs [bitmap index
scans](https://www.postgresql.org/docs/current/indexes-bitmap-scans.html)
to retrieve data.

This approach, while beneficial in many scenarios, introduces a
potential I/O bottleneck. The bitmap index scan first identifies the
required database blocks and then utilizes a bitmap to access the
corresponding rows from the table's heap. This subsequent "bitmap heap
scan" can result in significant I/O overhead, particularly when queries
return a substantial number of rows across numerous data pages.

## Impact:

Under heavy load or with queries filtering for a wide range of events
across multiple aggregate types, this increased I/O activity may lead
to:

- Increased query latency.
- Elevated disk utilization.
- Potential performance degradation of the event store and dependent
systems.

# How the Problems Are Solved

To address this I/O bottleneck and further optimize query performance,
the projection handler has been modified. Instead of employing multiple
OR clauses for each aggregate type, the aggregate and event type filters
are now combined using IN ARRAY filters.

Technical Details:

This change allows the PostgreSQL query planner to leverage [index-only
scans](https://www.postgresql.org/docs/current/indexes-index-only-scans.html).
By utilizing IN ARRAY filters, the database can efficiently retrieve the
necessary data directly from the index, eliminating the need to access
the table's heap. This results in:

* Reduced I/O: Index-only scans significantly minimize disk I/O
operations, as the database avoids reading data pages from the main
table.
* Improved Query Performance: By reducing I/O, query execution times are
substantially improved, leading to lower latency.

fix(eventstore): precise decimal (#8527) 
# Which Problems Are Solved

Float64 which was used for the event.Position field is [not precise in
go and gets rounded](https://github.com/golang/go/issues/47300). This
can lead to unprecies position tracking of events and therefore
projections especially on cockcoachdb as the position used there is a
big number.

example of a unprecies position:
exact: 1725257931223002628
float64: 1725257931223002624.000000

# How the Problems Are Solved

The float64 was replaced by
[github.com/jackc/pgx-shopspring-decimal](https://github.com/jackc/pgx-shopspring-decimal).

# Additional Changes

Correct behaviour of makefile for load tests.
Rename `latestSequence`-queries to `latestPosition`

feat(v3alpha): web key resource (#8262) 
# Which Problems Are Solved

Implement a new API service that allows management of OIDC signing web
keys.
This allows users to manage rotation of the instance level keys. which
are currently managed based on expiry.

The API accepts the generation of the following key types and
parameters:

- RSA keys with 2048, 3072 or 4096 bit in size and:
  - Signing with SHA-256 (RS256)
  - Signing with SHA-384 (RS384)
  - Signing with SHA-512 (RS512)
- ECDSA keys with
  - P256 curve
  - P384 curve
  - P512 curve
- ED25519 keys

# How the Problems Are Solved

Keys are serialized for storage using the JSON web key format from the
`jose` library. This is the format that will be used by OIDC for
signing, verification and publication.

Each instance can have a number of key pairs. All existing public keys
are meant to be used for token verification and publication the keys
endpoint. Keys can be activated and the active private key is meant to
sign new tokens. There is always exactly 1 active signing key:

1. When the first key for an instance is generated, it is automatically
activated.
2. Activation of the next key automatically deactivates the previously
active key.
3. Keys cannot be manually deactivated from the API
4. Active keys cannot be deleted

# Additional Changes

- Query methods that later will be used by the OIDC package are already
implemented. Preparation for #8031
- Fix indentation in french translation for instance event
- Move user_schema translations to consistent positions in all
translation files

# Additional Context

- Closes #8030
- Part of #7809

feat(eventstore): increase parallel write capabilities (#5940) 
This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and  [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.
