Summary

Support reported that order search missed matches when the typed case differed from stored data (e.g. "JOHN" returned nothing, though John Smith has two orders). Search now ignores letter case for order number, customer name, and email, so staff find the same orders whatever case they type.

Ticket / Assignment

Ticket: Inconsistent order search behavior with uppercase input
Assignment:

What changed

apps/api/src/orders/order-repository.ts: listOrderSummaries compares lower(column) with lower(search) in its existing instr() checks. Root cause: SQLite instr() is case-sensitive. instr is kept (not LIKE) so % and _ in search text stay literal.
apps/api/src/orders/orders-routes.test.ts: two API regression tests — customer name searched as JOHN SMITH (matches only through the name column) and order number searched as ord-1001.

How to test

bun run check
bun run test

Both new tests failed before the fix (returned []) and pass after it; order-routes file 8/8, full suite 12/12, typecheck clean.
Mutation check: removing lower() from the name comparison alone makes the customer-name test fail, confirming it pins the name column.
bun run build:web was not run: no web code changed, and its Tailwind step rewrites app.css.

Manual checks:

GET /api/orders?query=JOHN, john, John each returned ORD-1001 and ORD-1003
GET /api/orders?query=ord-1003 returned ORD-1003; no query returned all 7 orders
Browser pass on the Order page has done

Screenshots or recordings

N/A (no UI change)

Risks / follow-ups

SQLite's built-in lower() only folds ASCII, so accented names (É vs é) still match case-sensitively. Follow-up if non-ASCII customer data matters.
Search still scans the table (unchanged; instr could not use an index before either).
Unrelated tooling note: root bun run seed:user waits on an interactive prompt; running it from apps/api with an employee argument works.

PR checklist

change is scoped to one ticket or one small reviewable concern
acceptance criteria were checked
code follows CONTRIBUTING.md
no unrelated refactor is mixed in
debug code and temporary logs are removed
relevant automated checks were run locally
changed behavior was manually tested when needed (over HTTP; browser pass pending)
known risks or follow-ups are called out

fix: make order search case-insensitive 94ebd0733a

Searching "JOHN" or "ord-1001" returned no orders because SQLite instr()
is case-sensitive. Compare lowercased values for order number, customer
name, and email. Adds API regression tests for both cases.

Search "JOHN SMITH" instead of "JOHN" so the regression test only matches
through the customer name column ("john" alone also matched the email),
ensuring case-insensitive name matching is verified on its own.

Probably better to move the lower() function to the search above, instead of casting lower 3x here.

PR Description and contents a little verbose, but otherwise a good job at getting the assignment test to pass.
