lot of small fixes

- adds tag serial debug in webflasher and power up/down buttons
- fixes bug where esp32-s3 connected via usb cdc slows down when no terminal connection is present
- fix: ghost tags reporting a different channel id than the AP are now ignored
- webflasher now ramps up/down power to prevent spikes
- bugfix: C6 doesn't get reset anoymore by the watchdog during flashing
- bugfix: C6 could go in flash mode unintended
- a failed connection during swd write blocks is now reported back instead of silently ignored
- added 4 areas of Sweden to day ahead price content
- new context menu option 'Delete all inactive tags' (only when right clicking on an inactive tag).
