Subject: [PATCH] smt2parser: realign `pop_app_frame` non-`expr_head` `else`
 block indentation (#9646)

This updates a formatting regression introduced in the `pop_app_frame`
non-`expr_head` path, where block indentation made control flow harder
to read. The patch is whitespace-only and keeps parser behavior
unchanged.

- **What changed**
- Reindented the `else` body in
`src/parsers/smt2/smt2parser.cpp::pop_app_frame` so nested `if/else`
structure is visually unambiguous.
- Removed trailing spaces on the `m_ctx.mk_app(symbol("select"), ...)`
lines in the same block.

- **Scope**
  - No control-flow, data-flow, or API changes.
  - No changes outside `pop_app_frame`.

```cpp
// Before
else {
local l;
if (m_env.find(fr->m_f, l)) {
    ...
}
else {
    ...
}
}

// After
else {
    local l;
    if (m_env.find(fr->m_f, l)) {
        ...
    }
    else {
        ...
    }
}
```
