- For development and maintenance: [tests], [ci], [docs], [maintenance].
- If it's a work in progress, consider creating this PR as a draft.
- Don't hesistate to ask for opinion and review in the community chats,
even if it's still a draft.
- Add the label `backport` if it's a bugfix that needs to be backported
to a previous version.

## What this PR does
Previously `_cluster.clusterissuer` controlled the ACME solver type
using
values `http01` / `cloudflare`, and every ingress template hardcoded
`cert-manager.io/cluster-issuer: letsencrypt-prod` with no way to
override it.
This PR adds new parameters in platform chart:
- `publishing.certificates.solver` (default `http01`)
- `publishing.certificates.issuerName` (default: `letsencrypt-prod`)
instead of single parameter before
- `publishing.certificates.issuerType`
Previous `certificates.issuerType` was renamed to `certificates.solver`;
Also its possible value
`cloudflare` was renamed to `dns01` to use standard ACME terminology.
New `certificates.issuerName` (default: `letsencrypt-prod`) — propagated
as
`_cluster.issuer-name` to all packages via `cozystack-values` then its
value appears in
`cert-manager.io/cluster-issuer` annotation across 8 templates of
ingresses in system applications.
`publishing.certificates.solver` can be set empty to clearly support
`selfsigned-cluster-issuer`,
or have any value, but it can be a bit confusing.
Operators can now point ingresses at any ClusterIssuer (custom ACME,
self-signed, internal CA) by setting `certificates.issuerName` without
touching individual package templates.
## Breaking changes
| What changed | Before | After |
|---|---|---|
| Solver key | `certificates.issuerType` | `certificates.solver` |
| Cloudflare solver value | `issuerType: cloudflare` | `solver: dns01` |
This changes handled by migration when upgrading cozystack from v1
or by `migration-to-v1.0.sh` script (also checked by migration later)
No actions from user needed.

```release-note
[platform] Added publishing.certificates.solver (http01/dns01) and
publishing.certificates.issuerName fields to allow configuring ACME challenge
type and ClusterIssuer per installation, replacing the old implicit issuerType field
[platform] Migration script and upgrade hook (migration 32) convert old
clusterissuer/issuerType fields to the new solver/issuerName fields
```

## Summary by CodeRabbit
* **Chores**
* Migrated certificate issuer configuration from legacy `issuerType`
field to new `solver` and `issuerName` fields system-wide.
* Automated migration script converts existing configurations, mapping
legacy values (cloudflare, http01) to new format.
* Updated all certificate-related templates to use new configurable
solver and issuer settings with sensible defaults.
