feat(files): default sort by updated and add updated sort option

[waleedlatif1]

Summary

• Default sort across Files, Knowledge Base, and Tables pages is now "Last Updated" (desc) instead of "Created"
• Added "Last Updated" option to the Files sort dropdown (KB and Tables already had it)
• Added updated_at column to workspace_files table; bumped on content update, rename, and restore
• Propagated updatedAt through WorkspaceFileRecord and API

Type of Change

• New feature

Testing

Tested manually — file list now sorts by most-recently-updated by default; renaming a file bumps it to the top.

PR Summary

Medium Risk
Moderate risk because it adds a new non-null DB column and changes default sorting behavior across multiple resource lists; potential issues are migration/backfill and any callers expecting uploadedAt-based ordering.

Overview
Updates Files/Knowledge Base/Tables listings to default sort by updated (desc) instead of created, and adds a “Last Updated” column + sort option to the Files table.

Introduces workspace_files.updated_at (non-null, default now()), propagates updatedAt through WorkspaceFileRecord (including mothership upload records), and bumps updatedAt on workspace file content updates, renames, and restores.

Greptile Summary

This PR adds an updated_at column to workspace_files, propagates it through WorkspaceFileRecord and all read/write paths, and changes the default sort for Files, Knowledge Base, and Tables pages from "Created" to "Last Updated" (desc). It also adds a "Last Updated" sort option and table column to the Files page, where it was previously missing.

Confidence Score: 5/5

Safe to merge — migration is additive, all read/write paths are correctly updated, and remaining findings are P2 style suggestions.

All P0/P1 concerns are absent: migration is a safe additive column with a default, TypeScript interface change is fully propagated across mapped call sites, and default sort fallback works correctly. The two open findings are P2 style suggestions (column order inconsistency and missing updatedAt bump on file materialization).

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/files/files.tsx	Adds 'Last Updated' column to table and sort dropdown, changes default sort to 'updated'; column order in COLUMNS array is inconsistent with sort dropdown order.
apps/sim/lib/uploads/contexts/workspace/workspace-file-manager.ts	Adds updatedAt to WorkspaceFileRecord interface and propagates it through all read paths; bumps updatedAt on content update, rename, and restore operations.
packages/db/migrations/0197_unknown_the_captain.sql	Adds updated_at column to workspace_files with DEFAULT now() NOT NULL; backfills existing rows to migration timestamp.
packages/db/schema.ts	Adds updatedAt: timestamp('updated_at').notNull().defaultNow() to workspaceFiles table definition, consistent with migration.
apps/sim/lib/copilot/tools/handlers/materialize-file.ts	Adds updatedAt to toFileRecord mapping but the materialize update itself does not bump updatedAt, so materialized files won't surface at the top of the default sort.
apps/sim/lib/copilot/tools/handlers/upload-file-reader.ts	Adds updatedAt to toWorkspaceFileRecord mapping; straightforward propagation change.
apps/sim/app/workspace/[workspaceId]/knowledge/knowledge.tsx	Changes default sort column from 'created' to 'updated'; safe since 'updated' was already a valid sort option.
apps/sim/app/workspace/[workspaceId]/tables/tables.tsx	Changes default sort column from 'created' to 'updated'; safe since 'updated' was already a valid sort option.
apps/sim/app/workspace/[workspaceId]/home/components/mothership-view/components/resource-content/resource-content.tsx	Adds updatedAt: STREAMING_EPOCH to the streaming placeholder object to satisfy the updated WorkspaceFileRecord interface.
