enhance(actions): replace ansi_up with first-party code (#38619)

Replaces the `ansi_up` dependency with first-party code and fixes a
number of bugs in turn.

- Faster rendering, around 7x for plain lines and 3x for colored ones.
- Render many SGR features like hyperlinks, blink, inverse, conceal,
strikethrough, overline, underline styles and underline color, including
`:` sub-parameters, which no longer swallow the codes after them.
- Drop OSC, DCS, SOS, PM and APC with their payload, ending them at BEL,
`ESC \` or the 8-bit ST. A truncated sequence is dropped instead of
corrupting a later line.
- A backspace moves the cursor back a column, so what follows overwrites
it, even across a style change.
- A style inside an OSC 8 label renders instead of leaking, and a
private CSI ending in `m` no longer resets the style.
- Log lines render as DOM nodes, never as markup, and only an `http(s)`
url becomes a link.
- Named colors render as CSS classes, only 24-bit color stays inline.
- Invisible text is now selectable, and the `z-index` workaround is
gone.
