`ProjectService` needs to be runtime configurable to determine whether ESM bases count as supported

Current evaluation

Enhancement: ProjectService.check_base_is_supported should be runtime-configurable so ESM bases count as supported, enabling Rockcraft's --pro feature to use ESM support as the --ignore=unmaintained cut-off. Triaged, open, no activity since creation ~11 months ago.

Suggested action: keep open

Reason: The issue is labeled 'Status: Triaged' and 'Type: Enhancement' and was filed by a maintainer (lengau) as part of the WIP --pro feature; Pro support was subsequently finalized in #1047 and pro_services is now plumbed into ProjectService (craft_application/application.py:546), but check_base_is_supported still unconditionally treats ESM bases as EOL, so the requested configurability remains unimplemented. No maintainer has closed or deprioritized it, so it should stay open despite ~11 months of inactivity.

Impact: 40 Quick Win: 24.0 Staleness: 65 Complexity: 40 Confidence: 75 Support Request: 0

Issue body

### What needs to get done When someone uses [`ProjectService.check_base_is_supported`](https://github.com/canonical/craft-application/blob/395771748cd6ce89aec80a69805d8082aaf21262/craft_application/services/project.py#L673), it currently errors if the base is ESM. This needs to be configurable though, so that when requested we count ESM bases as supported. ### Why it needs to get done So that the WIP `--pro` feature for Rockcraft can set ESM support (or perhaps the end of pro support? Could these differ @cjdcordeiro?) as the cut-off date for `--ignore=unmaintained`
