fix: Provide clear error for empty tuple/array in from

[max-sixty]

Summary

Fixes #4317 by replacing panic with a user-friendly error message when using from {} or from [].

Changes

• Modified prqlc/prqlc/src/semantic/resolver/functions.rs to detect empty tuples/arrays and provide clear error messages
• Updated test snapshots in bad_error_messages.rs to expect new error format

Before

The application panicked (crashed).
Message: called `Option::unwrap()` on a `None` value
Location: prqlc/prqlc/src/semantic/resolver/functions.rs:279

After

Error:
   ╭─[ :1:6 ]
   │
 1 │ from {}
   │      ─┬
   │       ╰── expected a table or query, but found an empty tuple `{}`
   │
   │ Help: an empty tuple cannot be used as a table
───╯

Test Plan

• All tests pass (607 tests)
• Handles both from {} and from [] cases
• Doesn't break std.from_text with empty data (which properly sets lineage)
• Code formatted with rustfmt
