Update in-tree `wal-restore` to use the new `barman-cloud` restorer APIs, resolving a bug that can cause replicas to enter a broken state that CNPG cant recover from. Local marker naming, WAL timeline parsing, and restore-result filtering policy now lives in `github.com/cloudnative-pg/barman-cloud/pkg/restorer`. depends on cloudnative-pg/barman-cloud#277 Signed-off-by: Jeremy Schneider <schneider@ardentperf.com>

A global end-of-WAL marker can be set by a parent-timeline prefetch miss and then consumed by a child-timeline restore request. In snapshot-restored replica flows, that can cause PostgreSQL to miss valid child-timeline WAL and replay wrong parent-timeline bytes. Reference cloudnative-pg/barman-cloud#276
