Remove empty Github service templates from db

See merge request gitlab-org/gitlab!18868

When creating a new Github integration, it looks for a service
record of the same type, but with the template flag set to true,
and clone its attributes before presenting the record to the user.

`https://gitlab.com/gitlab-org/gitlab/merge_requests/15737/diffs`
added `static_context` as a default attribute on for
this service but it clashes with the empty template on .com.

This commit removes Github templates that have `nil` or `{}`
as properties, allowing new services to set the `static_context`
default value from the code.

Dynamically set db pool size in Puma

Closes #32562

See merge request gitlab-org/gitlab!19286

Before Puma, we had 1 rails process talk to the database
at any given time, which meant a connection pool size of 1
was sufficient to support that model. With Puma and its worker
thread pool, there can now be many threads simultaneously
trying to talk to the database. This change makes sure that
we allow the db pool size to scale along with the maximum
number of worker threads configured.

Fixes a bug where hidden.bs.dropdown was manually triggered
but the dropdown was not actually hidden. Triggering the event
caused the event handlers to be unloaded. The events are supposed
to be attached again when the dropdown is opened but in this case
the dropdown is still open.

Move Vulnerabilities API to Vulnerability Findings API

See merge request gitlab-org/gitlab!19029

The /api/v4/project/:id/vulnerabilities is going
to be used for serving the new Vulnerability model
instances for First-class Vulnerabilities feature.
The previous behavior (responding with
Vulnerabilities::Occurrence) is moved to
/api/v4/project/:id/vulnerability_findings path
unconditionally (regardless of the feature flag).
This is a breaking change.

Fixes missing target types in `TargetTypeEnum` and separates the
EE-specific types.

Adds `calls_gitaly` for the `TodoType#body` field, as an error is raised
when requesting the `todo.body field` for a `Commit` `Todo`:

    RuntimeError (Gitaly is called for field 'body' on Types::TodoType
    - please either specify a constant complexity or add
    `calls_gitaly: true` to the field declaration)

When the `Todo` (a polymorphic model) has a `target_type` of `Commit`,
requesting the `body` field calls Gitaly (`Todo#body` calls
`Todo#target` which fetches the `Commit` from Gitaly) and we get the
above error.

I've set `calls_gitaly: true` for the `TodoType#body` field (affecting
all Todos, regardless of the `target_type`) in order to avoid the error,
while we work out a better solution.
