Subject: [PATCH] fix(web): resolve all 607 lint warnings

disable react-in-jsx-scope (585 false positives with jsx: react-jsx)

fix no-unsafe-enum-comparison (7):
- import GitObjectType/GitRefType enums from codegen
- compare against enum members instead of string literals

fix no-unsafe-type-assertion (8):
- replace `as string` casts with typeof guards in validateSearch
- add type guard functions for union validation

fix no-array-sort (3):
- replace `[...arr].sort()` with `arr.toSorted()` (ES2023)
- add ES2023 to tsconfig lib

fix remaining:
- rename shadowed `_` variable (no-shadow)
- move handleSignOut to module scope (consistent-function-scoping)
- suppress import/no-unassigned-import for CSS import
