Use full disk - recycle. (never delete) 
**Is your feature request related to a problem? Please describe.**
no.

**Describe the solution you'd like**
Using full disk with periodically checks in order to delete the oldest video to make more space than 5gb 
(assuming 5gb is a safe-space for OS. updates etc)

**Describe alternatives you've considered**
 Altering a few lines at the cleartimer.js  at the line 62 and bellow? i will provide an example.

`      if (recRemoveAfter) {
        const recordings = Cleartimer.#recordingsDB.chain.get('recordings').cloneDeep().value();

        //will need to check free space later.
        const recPath = Cleartimer.#recordingsDB.chain.get('path').cloneDeep().value();

        //Change the (for loop) array to loop with shorting from lowest unix timestamp first to higher (oldest)  

        for (const recording of recordings.sort(({ timestamp: a }, { timestamp: b }) => a - b)) {


          //Recycle option? considering frontend hides 100days for this. (time == 100)

          if (recRemoveAfter == 100) {
            //update available disk space?
            let diskSpace = await checkDiskSpace(recPath);

            //if we left less than 5gb free space, remove that file if still less than 5gb
            if ((Math.round(diskSpace.free / 1e9) < 5)) {
              Cleartimer.#recordingsTimer.set(recording.id, false);
              await Cleartimer.#clearRecording(recording.id);
            }




          } else {
            let timestampNow = moment();.................................................................`

**Additional context**
Im not sure how often this is called in order to work smoothly and how these timers actually work , i would like an explenation tho.
