fix(persistence): strip single quotes from search query values

[v1r3n]

Summary

1. Fix: single quotes not stripped from search query values

• The query value parser in SqliteIndexQueryBuilder and PostgresIndexQueryBuilder only stripped double quotes and parentheses from condition values, but not single quotes
• Queries like workflowId='some-id' matched against the literal value 'some-id' (with embedded quotes) instead of some-id, returning zero results
• This also broke the internal ExecutionDAOFacade.getWorkflowsByCorrelationId code path which constructs queries with single quotes
• Fix: changed regex character class from [\"()] to [\"'()] in both query builders

2. Fix: IDGenerator crashes on invalid property values

• IDGenerator used @ConditionalOnProperty(havingValue=\"default\", matchIfMissing=true), so setting conductor.id.generator to any value other than "default" (even a typo) would prevent the bean from being created, crashing the server
• Fix: replaced with @ConditionalOnMissingBean on a @Bean method in ConductorCoreConfiguration — the default IDGenerator is always available unless a custom implementation bean is explicitly provided

Test plan

Integration tests (SQLite + Postgres, real DB, Spring context, Flyway migrations)

• testSearchWorkflowSummaryWithSingleQuotes — single-quoted workflowId search returns correct WorkflowSummary
• testSearchWorkflowsWithSingleQuotes — single-quoted workflowId search returns correct workflow ID string (SQLite)
• testSearchWorkflowsWithSingleQuotedMultiCondition — multi-condition queries with single quotes (mimics getWorkflowsByCorrelationId)

E2E tests (full Conductor server + Postgres, Docker, HTTP client)

• testBasicWorkflowSearch — existing search by workflowType IN
• testSearchByWorkflowIdWithDoubleQuotes — baseline workflowId search
• testSearchByWorkflowIdWithSingleQuotes — validates the single-quote fix end-to-end
• testSearchByWorkflowTypeWithSingleQuotes — workflowType with single quotes
• testSearchWithMultipleConditionsAndSingleQuotes — multi-condition query mimicking getWorkflowsByCorrelationId
• testSearchWithPaginationAndSort — pagination and sort with single-quoted queries

Existing tests

• All existing tests continue to pass
