refactor(admin-api): add cursor-based pagination to list revisions endpoint

[shiyasmohd]

• Adds cursor-based pagination (last_id) to the GET /revisions endpoint and ampctl table list command, following the same pattern used by jobs::list
• Merges the separate list (cursor-only) and list_all (active-filter-only) functions in physical_table_revision into a single list function that supports both cursor pagination and active filtering
• Removes the now-redundant list_all and sql::list_all functions
• Add tests
