feat(sql-workspace): run the script one statement at a time, Ctrl+H opens history (#1148)

[ZhuchkaTriplesix]

Refs #1148

Changes

• Run script (F5, Ctrl/Cmd+Shift+Enter, Execute button): the selection, otherwise the whole text, runs one statement at a time. The first error stops the run; the status names the statement and its line (Statement 3 of 5 failed (line 3): …) and the caret moves to it.
• A script that succeeds shows the last result set and 5 statements · 12 rows affected. The destructive check runs once, over the text that will run.
• Run statement (Ctrl/Cmd+Enter) keeps running the statement under the caret.
• The Execute button has a ▾ menu with Run statement and Run script, each showing its shortcut.
• Ctrl/Cmd+H opens query history when the SQL workspace has focus.
• F11 is removed from the shortcut reference.
• Tests: caret run picks only the statement under the caret; a script stops at the first error with the statement and line; a successful script reports statements and rows.

Not in this PR

• The splitter with ranges, and its unit tests, were already on dev.
• The test that compares the SQL Editor section of the reference with the workspace bindings is not written yet.
• The reference lists F5 as "Refresh schema" under Navigation & App, while F5 runs the script in the SQL editor. This was already the case and is not changed here.
• The skipped test only the selected text runs when there is a selection is not re-enabled.
