Subject: [PATCH 1/2] fix: make gitly compile with current V

Master did not build at all. Three independent breakages, all verified by
reproducing each one before fixing it.

1. 32 vweb route handlers were declared without `mut ctx Context`.

   Current vweb dispatches `app.$method(mut user_context, ...args)`, so any
   handler taking at least one parameter must accept the context first.
   Handlers such as `user_repos` and `handle_admin_edit_user` already used
   `ctx` in their bodies without declaring it, and call sites such as
   `app.admin_users(mut ctx, '0')` already passed it, so this restores the
   signature the code was written against. `method.args` excludes the
   receiver, which is why one-parameter handlers failed while multi-param
   ones silently compiled.

2. `struct FileInfo` in repo/file.v collided with `os.FileInfo`.

   Substituting it into the `api.ApiSuccessResponse[T]` generic made V
   resolve the bare name in the wrong scope, emitting `os__FileInfo` as the
   declaration and `main__FileInfo` as the initialiser:

     src.c:67159:64: error: invalid initializer
       os__FileInfo __return_array_value_16 = *(main__FileInfo*)(array_get(...));

   Renamed to `RepoFileInfo`, which no stdlib type shadows.

3. `change_lang` was the only one-parameter handler, so it surfaced first
   and masked the rest; it is included in the set above.

Verified:
  - `v -d sqlite -o gitly.exe .` exits 0 and produces the binary.
  - `v -d sqlite test utils_test.v` -> 1 passed, 1 total.
  - `git diff --stat` touches only .v files; no build artifacts staged.

Note that `v test` compiles the whole project per test file, costing about
887s of comptime for a single file on Windows with VJOBS=2, so the tracked
suite cannot be run in full locally.
