Task 11.4. Extends resolveTemplate to use buildEoiContext when interestId
is provided, populating the new yacht.*, company.*, owner.* token scopes
from the shared EOI context. Legacy non-EOI templates still resolve via
direct client/berth/port lookups. Deprecated client.yachtName /
client.companyName / client.yacht*Ft tokens are removed from the catalog;
PR 12 will drop the backing columns. berth.mooringNumber is relaxed to
required:false so welcome-letter-style templates without a berth context
no longer trip the required-merge-field check.
