[Feature Request] Allow copying Base cell values, including Formula results, with Ctrl/Cmd+C

Feature request

It should be possible to copy the value of a focused cell in a Base using Ctrl+C / Cmd+C.

This is especially important for Formula properties because formula cells are read-only and there currently seems to be no convenient way to copy their computed result.

Current behavior

1. Create a Base.
2. Add one or more properties and a Formula property.
3. Let the Formula return a text value.
4. Focus the Formula cell.
5. Press Ctrl+C / Cmd+C.
6. Paste somewhere else.

Nothing is copied.

Double-clicking the Formula cell opens the formula editor, which allows editing the formula expression itself, but does not provide a convenient way to copy the computed value.

Expected behavior

When a Base cell is focused, pressing Ctrl+C / Cmd+C should copy its value to the clipboard.

For a Formula property, this should copy the computed result, not the formula source expression.

For text values containing line breaks, the line breaks should be preserved in the clipboard.

For example, a Formula may generate:

./config.sh \
  --url https://github.com/example/repository \
  --token 'example' \
  --name example-runner \
  --labels example

Copying the Formula cell should put that complete multi-line value into the clipboard.

Motivation

Bases can be useful not only for calculations but also for generating text from structured properties.

One example is a small command/script generator:

• Project: Text
• Repository: Text
• Download URL: Text
• Script: Formula

The Formula combines the input properties into a ready-to-use shell script. Docmost already handles the calculation perfectly, but the generated result cannot conveniently be copied out of the Base.

Being able to copy a focused cell value would also make Base interaction feel more consistent with spreadsheet/database applications.

Possible UX

At minimum:

Ctrl+C / Cmd+C on a focused cell → copy the cell value

Optionally, a Copy value action in the cell context menu or for read-only cells could make the feature discoverable for mouse users as well.

For Formula cells, the copied value should always be the evaluated result.
