GivTCP REST is now a component, Octopus fixes, Misc

What's Changed

Major re-factor GivTCP REST is now its own component

In theory this will have no impact, but its a big change as GivTCP REST is no longer part of the main inverter path and instead lives in a component with its own HA controls/sensors.

• refactor(givtcp): move GivTCP REST handling into its own component by @springfall2008 in #4864
• Let an apps.yaml energy sensor win over GivTCP auto-configuration by @springfall2008 in #4959

• fix(inverter): take the GE battery rate from battery_rate_max when there is no charge power register by @springfall2008 in #4954
• fix(inverter): model the reserve floor the register will accept, not just set_reserve_min by @springfall2008 in #4956
• fix(octopus): don't replenish the IO low-rate slot cap mid-window at midday by @mgazza in #4951
• fix(carbon): cope with the carbon forecast running out before the plan ends by @springfall2008 in #4958
• fix(octopus): price completed IOG dispatches off-peak regardless of location by @springfall2008 in #4957

Performance improvements

• perf: reduce Predbat's idle memory footprint by @springfall2008 in #4955
