When 5+ users edit concurrently, revision gaps trigger the Stale state
which throws 'Ignored server-side change.' on incoming operations. This
causes document divergence, silent data corruption, and eventually
force-resets that discard local edits.
Changes:
- Stale/StaleWithBuffer.applyServer: buffer incoming operations instead
of throwing, apply them sequentially after missing ops arrive
- Stale.applyClient: carry pendingOps to StaleWithBuffer on transition
- editor-socketio-server: retry-based force-reset (3 failures) instead
of immediate nuclear reset on any OT error
- hex2rgb: defensive null checks for old non-hex color records

The hex2rgb function seems to previously have been available globally.
It probably got lost in the great Webpack refactoring and nobody noticed
that.
This copies the function into its own file (to make importing it easy)
and adds an import in index.js.
