refactor: rename ScadaLink → ZB.MOM.WW.ScadaBridge (code + projects + namespaces)

Solution + 23 src projects + 26 test projects renamed; folders, csproj,
namespaces, and ScadaLinkDbContext/ScadaBridgeDbContext class updated.
ActorSystem "scadalink" → "scadabridge", Akka seed-node URLs migrated.
SQL roles/logins, LDAP domains, CLI command name, and CLI config dir
(~/.scadalink → ~/.scadabridge) also renamed.

Build green; 5 Host.Tests fail awaiting SQL login rename in next commit.
Pre-existing StaleTagMonitor timing flakes unchanged.

Rename script committed at tools/rename-to-scadabridge.sh.

+/// <remarks>
+/// <para>
+/// The hosted service drives a daily roll-forward of
+/// <c>pf_AuditLog_Month</c>: each tick reads the current max boundary and
+/// SPLITs new monthly boundaries until at least
+/// <see cref="LookaheadMonths"/> future months are covered. The 1-month
+/// default is intentionally conservative — anything less risks an
+/// end-of-month race where inserts land in the unbounded tail partition;
+/// anything more wastes nothing but represents premature commitment.
+/// </para>
+/// <para>
+/// The 24-hour cadence is the cheapest interval that still guarantees
+/// at-most-one missed boundary in steady state (even a hard failover the
+/// hosted service can recover on its very next tick). Lowering this below
+/// an hour would generate more metadata churn than it saves.
